Émile Gilliéron

From 1894, Gilliéron maintained a business producing replicas of archaeological finds, particularly metal vessels, which were sold to museums and collectors across Europe and North America. This enterprise grew particularly successful after Gilliéron introduced his son, also named Émile, into the business around 1909. The Gilliérons' work has been credited as a major influence on the public and academic perception of Greek antiquity, particularly Minoan civilisation, and with disseminating the influence of ancient cultures to modernist writers, artists and intellectuals such as James Joyce, Sigmund Freud and Pablo Picasso. Many of Gilliéron's restorations were made from highly fragmentary evidence, and he often made bold, imaginative decisions in reconstructing what he believed to be the original material. In several cases, his hypotheses have been challenged or overturned by more recent study. Gilliéron frequently muddied the distinction between his own restorations and the original material, and was criticised in his day for overshadowing ancient material with his own creations. He was also likely involved in the illegal export of forged antiquities from Greece, and has been accused of direct involvement in the manufacture of faked objects.

Louis Émile Emmanuel Gilliéron was born on 24 October 1850 in Villeneuve, Switzerland, the second of four sons of Jean-Victor Gilliéron and Méry Ganty. The Gilliéron family were originally French Protestants from the south-eastern Dauphiné region of France, who fled from religious persecution to Geneva in the eighteenth century. His father, a language professor in the Progymnasium in La Neuveville near Bern, and later in the Gymnasium for girls in Basel, was also a respected amateur geologist and paleontologist. Émile attended the Progymnasium in La Neuveville, then studied at the trade school (Gewerbeschule) in Basel from 1870 to 1872. From 1870 to 1871, he was an apprentice in the lithography studio of Johannes Jakob Tribelhorn at Saint Gall, an experience to which he later attributed the exceptional precision of his drawings of ancient artefacts. In 1872, he moved on to the Royal Academy of Fine Arts in Munich, where he studied with Johann Georg Hiltensperger. He completed his education in 1874–1875 at the École Nationale Supérieure des Beaux-Arts in Paris, in the studio of the academic painter Isidore Pils. While at the École des Beaux-Arts he also studied ancient art with the archaeologist Léon Heuzey, a member of the Académie des Inscriptions et Belles-Lettres and a conservator of antiquities at the Louvre. • Illustration — Watercolor and gouache of the village of Kastri (ancient Delphi), painted by Gilliéron in 1876 Following the death of Pils in 1875, and with the encouragement of Heuzey, Gilliéron accompanied his elder brother, the classicist Alfred Gilliéron, on a voyage to Albania and Greece. The brothers arrived in Athens in the autumn of 1876, and by the following year Émile had established himself in the city as an artist and art teacher. He purchased a house at 43 Skoufa Street in the fashionable Kolonaki district, which served as his home and atelier throughout his life. Among the students to whom he gave lessons in drawing and painting in the 1880s were the sons of George I of Greece, whose patronage gave him access to the upper echelons of Greek society. George's younger son Nicholas enjoyed the lessons and looked back on Gilliéron with fondness, later mentioning Gilliéron in his autobiography; his elder brother, the future king Constantine, later served as the president of the Archaeological Society of Athens. In 1899–1900 Gilliéron taught the Italian artist Giorgio de Chirico, who was born and educated in Greece, and whose paintings drew on the archaeological and mythological themes characteristic of Gilliéron's work. According to de Chirico, his lessons consisted primarily of copying "a lot of prints", possibly those of archaeological finds Gilliéron was engaged in restoring and replicating.

• Illustration — Drawing by Gilliéron of a red-figure cup from Tanagra, depicting a symposiast reciting a line of poetry by Theognis Within a few years of his arrival in Athens Gilliéron had already begun to specialize in the work for which he was best known: that of an archaeological draughtsman. Writing after his death in 1924, the archaeologist Gerhart Rodenwaldt, director of the German Archaeological Institute at Athens, suggested that Gilliéron lacked the artistic creativity needed to make a living purely as a creative artist, and this, together with the economic conditions in Athens at the time, compelled him to turn more and more to archaeological illustration. According to Rodenwaldt, "he devoted the full intensity of his ebullient disposition to this work, although he never fully got over the tragedy of abandoning his original creations". Nevertheless, while commercial archaeological work became the focus of his business, he continued to produce landscapes and other paintings for his private satisfaction, most of which remained in the possession of his family. Gilliéron's contemporaries and the archaeologists who worked with him praised the accuracy of his draughtsmanship and his ability to reproduce the fine decoration on objects such as vases and gemstones. They also valued his skill as a painter, which he relied upon to restore the appearance of damaged objects and to document the original colouring of ancient sculptures. These skills were in demand, as photography was expensive and the results difficult to guarantee; photography was also generally unable to convey colour, whereas Gilliéron painted in bold watercolour, sometimes at a 1:1 scale. His fees were accordingly high. Gilliéron's archaeological drawings and paintings began to appear in the publications of the German Archaeological Institute as early as 1879. His close association with the Institute continued throughout his career: among the German archaeologists with whom he collaborated were Wilhelm Dörpfeld, Ernst Fabricius, Adolf Furtwängler, Paul Hartwig, Georg Karo, Gerhard Rodenwaldt, Theodor Wiegand, and Franz Winter. One of his first clients was Heinrich Schliemann, the excavator of the sites of Troy, Tiryns and Mycenae, for whom he worked as a painter, draughtsman, and conservator from 1877 until Schliemann's death in 1890. In 1884, Schliemann hired him to produce reconstructions of the frescoes he had unearthed at the Mycenaean citadel of Tiryns in the Argolid; Gilliéron reconstructed one fresco to show a man dancing upon a bull, an image which became famous as the cover illustration of Schliemann's volume publishing the results of his excavations. • Illustration — Watercolor by Gilliéron of a pediment from the Athenian Acropolis depicting the apotheosis of Herakles In the 1880s, Gilliéron produced a series of drawings and watercolours of vases, sculptures, and other objects discovered on the Acropolis of Athens during the excavations directed by Panagiotis Kavvadias. Many of his reproductions of vase paintings appeared after his death in the publication by the German Archaeological Institute of the ceramic finds from the Acropolis, which used his drawings when photographs alone were inadequate to illustrate the decoration of the vessels. His large-scale watercolours of sculpture, including the poros architectural sculpture from the Hekatompedon and other Archaic buildings on the Acropolis, and the marble korai and other works found in the debris associated with the Persian invasion of Athens in the early 5th century BCE, provided an important record of the original colouring of these objects, which was often clearly visible at the time of excavation but deteriorated quickly thereafter. These paintings gained wide exposure outside Greece, as Gilliéron was commissioned to produce additional copies for private collectors and museums. A collection of twenty-six watercolours and tinted photographs, originally made in 1883 and 1886 for the American architect and art critic Russell Sturgis, were later acquired by the Museum of Fine Arts in Boston, where they were displayed in 1891 in an exhibition on ancient polychromy organised by Edward Robinson, the museum's curator of classical antiquities. A similar exhibition at the Art Institute in Chicago in 1892 also included watercolours and photographs loaned by Sturgis. After Robinson moved to the Metropolitan Museum of Art in New York City in 1906, that institution too purchased hundreds of paintings, replicas, and other objects from Gilliéron and his son, including watercolours of the architectural sculpture from the Acropolis. Other copies were acquired by the Humboldt University of Berlin. Some of Gilliéron's watercolours of sculpture from the Acropolis were exhibited in the Greek pavilion at the Exposition Universelle in Paris in 1889, greatly enhancing his profile and reputation. In 1886, Gilliéron was hired to assist in the rescue excavation of Psychro Cave in eastern Crete, conducted under the Syllogos of Candia, a local archaeological society. Gilliéron made painted reconstructions of the bronze votive objects deposited in the cave, many of which were in damaged or fragmentary condition. In the same year, he was commissioned by the classical archaeologist Carl Robert to paint ancient sarcophagi for the latter's Corpus der Antiken Sarkophagreliefs ("Corpus of Ancient Sarcophagus Reliefs"); he contributed drawings to all four volumes of the corpus, which were published periodically until 1919. From 1888 to 1889, he worked with Paul Wolters at the Theban Kabeirion in Boeotia. Wolters, then the second secretary of the German Archaeological Institute and later a professor at the Ludwig-Maximilians-Universität München and director of the Munich Glyptothek, remained a close friend and supporter for the rest of Gilliéron's life. For a report published in 1893, Gilliéron illustrated the pottery found by Valerios Stais during the excavation of the tumulus of the Athenians at Marathon from 1890 to 1891. Following the discovery of the painted metopes of the Temple of Apollo at Thermon in 1898, he produced a group of preliminary drawings published in 1903, followed by more complete watercolours of the mended fragments published in 1908, which were widely reproduced in handbooks on Greek art. His work as a draughtsman was not confined to antiquities: in 1880, he accompanied Spyridon Lambros to Mount Athos in order to make copies of the frescoes of the Byzantine painter Manuel Panselinos in the church of Protaton at Karyes, and at some point before 1885, he was hired by the Marquess of Bute to copy the poorly preserved Christian frescoes in the Parthenon and the church of the Megali Panagia in Athens, as well as other paintings at Mistra in Laconia. Although Gilliéron was active chiefly in Greece, he occasionally worked in other Mediterranean countries as well. In 1893, he was commissioned by Robert, who had recently become the director of the archaeological museum at the University of Halle, to make copies of Roman panel and wall paintings from Pompeii and Herculaneum for the museum collection. Robert had received a donation from Halle banker Heinrich Franz Lehmann to fund the work, and had been referred to Gilliéron by their mutual friend Paul Wolters. Gilliéron made two trips to Italy: during the first, in 1893, he produced watercolour copies of six ancient paintings on marble panels in the National Archaeological Museum in Naples, five of which had been found at Herculaneum and one at Pompeii. His work was supervised by August Mau, an excavator at Pompeii and an authority on Roman painting, who approved the accuracy of the copies. Several of the marble panels had been known since the 18th century and they were widely described as "monochrome" paintings, but Gilliéron's reproduction of the surviving traces of colour allowed Robert to recognize them as polychrome works, nearly a century before this conclusion was widely accepted by other scholars. Gilliéron himself suggested a second trip to Italy in the summer of 1896, perhaps because the unsettled political situation in Greece, on the eve of the Greco-Turkish war of 1897, may have disrupted some of his other projects. During this visit he made copies of six additional Pompeiian wall paintings with mythological subjects, some in museum in Naples, others still in situ at the archaeological site. For the German Egyptologist Friedrich Wilhelm von Bissing Gilliéron also made paintings of the Hellenistic and Roman tombs at Kom el-Shogafa in Alexandria, Egypt.

• Illustration — Two replica Vapheio cups made by Gilliéron's company From 1894, Gilliéron established a business, in collaboration with the German metalworking firm Württembergische Metallwarenfabrik Geislingen (WMF) of Geislingen an der Steige, manufacturing replicas of archaeological artefacts for sale to museums. A particular area of focus was the production of replicas of metal objects, using electrotyping from moulds made from the originals. According to Wolters, Gilliéron was as interested in the technical problems as he was in the artistic ones, and in the case of damaged originals his reproductions went beyond mere copies by reuniting broken fragments and restoring missing pieces. In order to explain and justify such reconstructions, Karo, at Wolters's suggestion, published a detailed analysis of Gilliéron's Mycenaean offerings, carefully distinguishing between the original parts and those that had been restored. The creation of these replicas led to a better understanding of ancient manufacturing techniques, and their distribution had a far-reaching effect on archaeological teaching. Some of his first endeavours with this technique were copies of the Vapheio Cups, two gold cups discovered by the archaeologist Christos Tsountas in a Mycenaean tomb in Laconia in 1888. Gilliéron reproduced the cups with the assistance of the Swiss metalworker Jules Georges Hantz, director of the Musée des arts décoratifs in Geneva, first in 1894 for Salomon Reinach, the curator of the French National Archaeological Museum, and subsequently for other customers as well. An exhibit of his replicas of objects from Mycenae was awarded a bronze medal at the Exposition universelle in Paris in 1900. By 1903, Gilliéron's company sold 90 different electrotyped Mycenaean artefacts, all manufactured by WMF; this figure rose to 144 by 1911 when Minoan artefacts were added to the list. An illustrated catalogue of the objects for sale was published in German, French, and English, with an introduction by Wolters, which described the original artefacts in detail and vouched for the accuracy of the reproductions. In 1918 a Gilliéron Vapheio Cup was offered for sale for 75 German Reichsmarks, approximately equivalent to £ in, while the most expensive item offered in 1914 was a copy of a bull's-head rhyton from Knossos, priced at 300 Reichsmarks. The firm also produced plaster casts of ancient sculpture, including korai from the Athenian Acropolis; some of these, painted to illustrate their original colouring and sold to the Metropolitan Museum in New York, have been placed on permanent loan to the Museum für Abgüsse Klassischer Bildwerke ('Museum of Casts of Classical Statues') in Munich.

Gilliéron took an active role in the promotion of the modern Olympic Games in Athens, and the iconography that he helped to establish for the games drew heavily on ancient Greek art. He was named the official artist of the games in 1896. The most widely distributed of his works were two series of commemorative postage stamps, the first issued in conjunction with the first modern Olympic games in 1896 and the second with the intercalated "Mesolympic" games in 1906. The stamps were the product of a collaboration between the archaeologist and numismatist Ioannis Svoronos, who chose the subjects; Gilliéron, who drew the designs; and the artist and engraver Louis-Eugène Mouchon, who engraved the metal plates. The stamps of 1896, which were printed in France and released to coincide with the opening of the games on 6 April (O.S. 25 March), included depictions of the Nike of Paionios and the so-called Hermes of Praxiteles, two works of sculpture recently discovered in the excavations at ancient Olympia, as well as a statue of a discus thrower traditionally attributed to the Greek sculptor Myron. Other stamps bore views of the Athenian Acropolis and the recently restored Panathenaic Stadium, and a Panathenaic amphora decorated with a figure of Athena. The sale of the stamps raised over 400,000 drachmes for the Olympic committee. The stamps produced for the games in 1906, created by the same three men and printed in England, included images of individual athletes and athletic events drawn from ancient vase paintings, coins, and works of sculpture. A scene of wrestlers, for example, was taken from an Athenian red-figure krater depicting the legendary wrestling match between Heracles and Antaeus, while a stamp with a figure of a discus thrower and a tripod reproduced the device on a coin from the island of Kos. Many of Gilliéron's designs were based not on the ancient works directly, but on line drawings in the Dictionnaire des Antiquités Grecques et Romaines by Charles Daremberg and Edmond Saglio, a French encyclopedia of the ancient Greek and Roman world published in ten volumes between 1877 and 1919. For the 1896 Olympics Gilliéron also designed the cover of the programme of events and the official report of the games. His painting combined ancient and modern Greek motifs — a view of the Acropolis and other ancient Athenian monuments, allusions to works of classical art, a modern Greek flag, and a figure of a woman in traditional Greek dress holding a victory crown of olive — and was later used as a poster by the International Olympic Committee. For the 1906 games he painted a series of postcards, including both representations of actual events in the stadium at Athens and imaginary compositions of ancient or allegorical figures. He also created preliminary designs for trophies, most of which remained unrealised. Some were replicas of ancient vessels, such as a Mycenaean cup found by Schliemann in Grave Circle A at Mycenae and a kantharos from the Theban Kabeirion. A series of circular plaster reliefs in the Gilliéron archive at the French School at Athens depict events in the pentathlon and seem to have been models for the decoration of proposed trophy cups; these, like the postage stamps, were based on ancient vase paintings and other works of art.

In the spring of 1900, the British archaeologist Arthur Evans was excavating the Bronze-Age ruins – which he named the "Palace of Minos" – of the Minoan site of Knossos on Crete. Gilliéron was visiting Knossos on 18 April, while Evans's draughtsman, Yannis Papadakis, was in the process of removing some of the first fresco fragments to be discovered in the so-called "Throne Room" of the palace: Gilliéron recognised the outline of a griffin in some of the fragments, which became an established part of Evans's reconstruction of the room's decoration. Evans wrote in his diary on that Gilliéron "began immediately to sort the fresco fragments like jigsaw puzzles" upon his arrival at Knossos. Evans found a number of frescoes requiring complex reconstruction, which he felt to be beyond the skill of Papadakis; he instead contracted Gilliéron to assist in their documentation and restoration. Gilliéron and his son Émile, born in 1885 and generally known as "Gilliéron fr", would work for Evans at Knossos for the next three decades. Evans constructed a gallery above the "Throne Room" to display copies of Gilliéron's work, replacing finds which had been removed for display at the Heraklion Archaeological Museum. Gilliéron also began, from 1901, to produce and sell replicas of the finds from Knossos. He offered versions reflecting the objects' state on discovery, as well as more extensively restored versions which purported to reproduce the objects as originally manufactured. In the case of objects such as the Harvester Vase from Hagia Triada, this required imaginatively reconstructing pieces of the object which had been lost or destroyed prior to discovery. • Illustration — Gilliéron's watercolour of the funerary stele of Stratonikos from Demetrias (1907) In 1907 Gilliéron was chosen by the Archaeological Society of Athens to produce watercolour copies of the painted funerary stelai from the Hellenistic city of Demetrias in Thessaly. In the Society's excavations at the site, directed by Apostolos Arvanitopoulos, more than 700 tombstones of the 3rd and 2nd centuries BCE, many with their polychrome decoration still well preserved, were found reused as building material in the fortifications of the city. Their importance was immediately recognized: a new museum to house the finds was built in Volos, a programme of conservation was begun, and Gilliéron was hired to make copies of some of the best preserved stelai in order to document their colouring while it was still fresh. Between 1907 and 1913 he made several trips to the Volos and painted at least fourteen of the tombstones. During the later trips he was accompanied by his son, who continued to work for Arvanitopoulos until 1917, although the archaeologist considered the son's work inferior to that of his father. Chromolithographic reproductions of ten of the elder Gilliéron's watercolours appeared in Arvanitpoulos's publication of the excavations in 1928. Gilliéron also made additional versions of some of the paintings, three of which were purchased by Robert for the archaeological museum at Halle. • Illustration — Gilliéron's reconstruction of a fresco from Tiryns, reconstructed as showing a man leaping over a bull Gilliéron père was hired between 1910 and 1912 by the German team, led by Georg Karo, continuing Schliemann's excavations at Tiryns; he restored the so-called "Shield Frieze" fresco from over two hundred fragments found in the inner forecourt of the palace. In some of his restorations at Tiryns, such as that of a woman carrying an ivory pyxis, Gilliéron disguised the distinction between original and restored material, creating the illusion that the entire fresco was original when in fact much of it was compiled from parts of other figures in the same scene. The two Gilliérons later worked with Karo on the publication of the finds from Schliemann's 1876 excavations of Grave Circle A at Mycenae, which Karo published between 1930 and 1933. Over time, Gilliéron transferred an increasing proportion of his work to his son, and renamed his business Gilliéron et fils ('Gilliéron and Son') around 1909–1910. Gilliéron fr has been credited by the archaeological historian Joan Mertens with improving the commercial success of their joint studio, and with extending its clientele to include patrons in Cuba and the United States as well as in Europe. Between 1906 and 1933, the Metropolitan Museum of Art purchased almost seven hundred artworks from the Gilliérons. The Gilliérons also worked on finds from Mycenae. Around 1906, Gilliéron père reproduced several of the objects from Grave Circle A, including the gold mask known as the "Mask of Agamemnon". Around 1918–1919, the Gilliérons replicated a painted stele discovered at Mycenae in 1893.

In his memoirs, de Chirico described Gilliéron as "a tall, robust man, with a thick white beard trimmed to a point". Rodenwaldt described his personality as "ingenious, passionate, clever, and humorous", and Paul Wolters wrote that he was "a man well aware of his own worth, but without ever becoming arrogant". His mother died five years after he was born, and two of his brothers also died early: his younger brother Gustave in 1866 while still a teenager, and his elder brother, the classicist Alfred Gilliéron, of typhus in Macedonia in 1878. His youngest brother, Jules Gilliéron, became a linguist at the École pratique des hautes études and co-authored the Atlas linguistique de la France. Gilliéron married Joséphine Zoecchi, also a painter, in 1884. They had five children, including Émile fr. Gilliéron père died in Athens on 13 October 1924, and was buried in the First Cemetery of Athens.

• Illustration — Gilliéron's drawing of a dagger from Grave Circle A at Mycenae, which Rodenwaldt cited as a particularly fine example of his work Mertens has written that Gilliéron's significance lay partly in being present at the unearthing of so many major archaeological discoveries, and being able to record their original colours before exposure to light and air damaged them. She also notes the size of Gilliéron's professional network and his ability to parlay that into financial opportunities – both of which she describes as "exceptional". • Illustration — Gilliéron's watercolour of a fresco of flying fish from Phylakopi, Melos Gilliéron's contemporaries praised his skill as a draughtsman, particularly the precision with which he reproduced the finest details of the works that he copied, and his ability to recognize faint traces of original decoration on badly damaged artefacts. His friend and colleague Wolters wrote that "one could not wish for a more skilled and conscientious draughtsman as a collaborator. He loved ancient art, he admired the subtle delicacy of the brushstrokes and engraved lines, and tried with success to achieve the same level of accuracy. Of the archaeological problems of restoration he had a complete understanding; above all, he was the most helpful assistant in recovering and clarifying almost-vanished traces on severely destroyed originals, and he always made every effort to interpret them correctly." Arvanitopoulos, for whom he produced watercolours of the painted funerary stelai from Demetrias, wrote that "the elder Gilliéron had an innate delicacy and elegance in the rendering of lines; he transmitted these qualities to the copies as well, so that many of them appear more graceful than the archetypes, without, however, departing from them in terms of the faithful rendering of even the smallest details." The purely artistic qualities of his watercolours have been admired more recently as well: Mertens describes the paintings of Acropolis sculpture in the collection of the Metropolitan Museum as "tours de force of the watercolorist's art", and praises "his mastery of the media, both in the pencil drawing and in the application of colour. Even with the use of technical aids to reproduce existing models or templates, the fluency of his execution over such large surfaces is exceptional, and, whether totally accurate or not, his sense of colour in many areas is ravishing." Wolters felt that many of these qualities could not be properly appreciated in the published reproductions of his works, because of the reduction in size and defects in printing. The archaeologists with whom he worked thought highly of Gillieron not just as an artist, but also as a collaborator who welcomed criticism and discussion. According to Rodenwaldt, Gilliéron believed that "a truly adequate copy could only be achieved through the constant collaboration of two personalities, an artist to execute the work and a critic to compare and correct it. He glady sought advice from scholars who seemed competent to him, and never felt entirely comfortable with work in which he had to do without such constant collaboration." Wolters similarly observed that "he demanded sharp criticism from us and expressed open displeasure if a drawing was accepted sight unseen", because this suggested to him that the client did not take the work as seriously as he did.

The Gilliérons have been accused of facilitating or participating in the creating and distribution of forged antiquities. The archaeologist Leonard Woolley, who visited Crete in 1923–1924, was present at a police raid on a workshop where local Cretan craftsmen produced forgeries of Minoan snake goddess figurines, and wrote that the forgers were working for Gilliéron. The historian Cathy Gere has called Gilliéron "almost certainly an important link in the chain between the forgers and the museums and dealers of Europe and America". While working with the Gilliérons on the Grave Circle A material, Karo came to suspect them of illicit activities. The archaeological historian Kenneth Lapatin has suggested that Gilliéron may have been the pseudonymous "Mr. Jones" from whom the collector Richard Berry Seager reported receiving the "Boston Goddess", a snake goddess figurine generally considered a forgery, in 1914; Gilleron may have offered the same object, or a similar forgery known as the "Baltimore Goddess", to Karo in the same year. Lapatin suggests that a remark of Karo's about "the men behind the scenes... [of] goldsmiths working to order as forgers" may have been a veiled reference to the Gilliérons.

• Illustration — Gilliéron's recreation of the Minoan fresco known as "Ladies in Blue", Knossos, re-restored after an earthquake by Gilliéron fr in 1927 MacGillivray has judged that Gilliéron produced "some of the most enduring watercolour reproductions of objects otherwise impossible to imagine because of their poor state of preservation". Lapatin credits Gilliéron and his son second only to Evans in creating the popular image of Knossos and Minoan society. The Gilliérons' prominent role in the reconstruction and publication of many of the most high-profile archaeological finds of their lifetime has led Mertens to conclude that "their images, in large measure, have defined our visual impressions of the great ancient cultures of the Greek world". In particular, their colourful reconstructions of archaic sculptures, whose painted colours could not at the time be shown by photography, played a major role in the developing interest of the public and of academics such as Gisela Richter and Edward Robinson in ancient polychromy. • Illustration — The "Priest-King Fresco", showing original fragments overlaid onto Gilliéron's reconstructions (including later adjustments made by Gilliéron fils) Replicas produced by Gilliéron and his son were purchased and displayed widely by European and American museums, as they were considerably cheaper than genuine ancient artefacts. Their work was acquired by London's South Kensington Museum, New York's Metropolitan Museum of Art, University College Dublin, the Winckelmann Institute of the Friedrich Wilhelm University of Berlin, Harvard University, the University of Montpellier in France, the Museum of Fine Arts in Boston, the Ashmolean Museum of the University of Oxford and the Fitzwilliam Museum of the University of Cambridge. The finds which were disseminated through their reconstructions have been cited as an influence on modernist writers, artists and intellectuals such as James Joyce, Sigmund Freud and Pablo Picasso.

Gilliéron's reconstructions often changed as his and his employers' assessments of the material evolved: a fresco at Knossos that he originally reconstructed as a young woman, labelled "Ariadne" by Evans after the mythical Cretan princess, became a figure of a male adolescent, described by the British archaeologist J. L. Myres as having a "European and almost classically Greek profile". When the English writer Evelyn Waugh visited Knossos in 1929, he wrote that it was impossible to gain an appreciation of Minoan painting there, since original fragments of fresco were crowded out by modern restorations, and judged that Evans and Gilliéron had "tempered their zeal for reconstruction with a predilection for the covers of Vogue". In 1969 the archaeologist Leonard Robert Palmer wrote a guide-book to the site of Knossos in which he described the "Ladies in Blue" fresco as "a spirited composition... by M. Gilliéron". Gilliéron may also have invented the scalloped pattern around the edge of the "Bull-Leapers Fresco" from Knossos, for which no ancient evidence has survived. Gilliéron often consciously blurred the distinction between original material and his own restorations, both at Tiryns and at Knossos, where he placed some of his reconstructions directly onto the ancient walls, surrounding the original fragments. In some cases, as with the "Blue Boy" fresco, Gilliéron's reconstruction has been shown to be incorrect: Gilliéron reconstructed the image with a figure of a boy, but further investigation showed that it was originally a monkey. • Illustration — A "snake goddess" figurine; an authentic example of the statue type of which the Baltimore and Boston goddesses are likely forgeries Referring to the Gilliérons' practice of combining fragments later evaluated to have come from discrete images, a modern study has concluded that they "created a decorative programme which, as it currently stands, never existed". Gilliéron's reconstruction of the so-called "Priest-King Fresco", which he developed from 1905 onwards, has been particularly challenged: the fresco was reconstructed from fragments which both Evans and Gilliéron initially believed to belong to different figures. The reconstruction was debated from the time of its publication in the 1920s. Between 1970 and 1990, the physician Jean Coulomb and the archaeologist Wolf-Dietrich Niemeier separately argued that the fragments did indeed belong to separate figures: Coulomb argued that the figure's torso belonged to a boxer, while Niemeier considered that the crown was more likely to belong to a female figure, either a sphinx or a goddess, in line with depictions of similar crowns in other Minoan paintings. It is also uncertain whether the figure's skin was originally coloured red, which would be typical of male figures in Minoan art, or white, which would be more typical of female figures.
