John of Worcester

1140) was an English monk and chronicler who worked at Worcester Priory. He is now usually held to be the author of the Chronicon ex Chronicis.

John of Worcester's principal work was the Chronicon ex Chronicis (Latin for "Chronicle from Chronicles") or Chronicle of Chronicles (Chronica Chronicarum), also known as John of Worcester's Chronicle or Florence of Worcester's Chronicle. The Chronicon ex Chronicis is a world history which begins with the Creation and ends in 1140. The chronological framework of the Chronicon was presented by the chronicle of Marianus Scotus (d. 1082). A great deal of additional material, particularly relating to English history, was grafted onto it. These include a rendition of the Genealogia Lindisfarorum (Latin for "Genealogy of the people of Lindisfarne"), a putative genealogical list found in this and some other medieval manuscripts.

The greater part of the work, up to 1117 or 1118, was formerly attributed to Florence of Worcester on the basis of the entry for his death under the year 1118, which credits his skill and industry for making the chronicle such a prominent work. In this view, the other Worcester monk, John, merely wrote the final part of the work. However, there are two main objections against the ascription to Florence. First, there is no change of style in the Chronicon after Florence's death, and second, certain sections before 1118 rely to some extent on the Historia Novorum ("History of New Things") of Eadmer of Canterbury, which was completed sometime in the period 1121–1124. The prevalent view today is that John of Worcester was the principal author and compiler. He is explicitly named as the author of two entries for 1128 and 1138, and two manuscripts (CCC MS 157 and the Chronicula) were written in his hand. He was seen working on it at the behest of Wulfstan, bishop of Worcester, when the Anglo-Norman chronicler Orderic Vitalis visited Worcester: • Ioannes Wigornensis a puero monachus, natione Anglicus, moribus et eruditione uenerandus, in his quæ Mariani Scotti cronicis adiecit, de rege Guillelmo et de rebus quæ sub eo uel sub filiis eius Guillelmo Rufo et Henrico usque hodie contigerunt honeste deprompsit. [...] Quem prosecutus Iohannes acta fere centum annorum contexuit, iussuque uenerabilis Wlfstani pontificis et monachi supradictis cronicis inseruit in quibus multa de Romanis et Francis et Alemannis aliisque gentibus quæ agnouit [...]. — "John, an Englishman by birth who entered the monastery of Worcester as a boy and won great repute for his learning and piety, continued the chronicle of Marianus Scotus and carefully recorded the events of William's reign and of his sons William Rufus and Henry up to the present. [...] John, at the command of the venerable Wulfstan bishop and monk [d. 1095], added to these chronicles [i.e. of Marianus Scotus] events of about a hundred years, by inserting a brief and valuable summary of many deeds of the Romans and Franks, Germans and other peoples whom he knew [...]."

The Chronicon survives in five manuscripts (and a fragment on a single leaf): • Illustration — 1128 sunspot drawing by John of Worcester. This is the earliest known drawing of a sunspot from anywhere in the world. • MS 157 (Oxford, Corpus Christi College). The principal manuscript, working copy used by John. • MS 502 (Dublin, Trinity College). • MS 42 (Lambeth Palace Library). • MS Bodley 297 (Oxford, Bodleian Library). • MS 92 (Cambridge, Corpus Christi College), continued with text from John of Taxster's Bury Chronicle. In addition, there is the Chronicula, a minor chronicle based on the Chronicon proper: MS 503 (Dublin, Trinity College), written by John up to 1123.

For the body of material dealing with early English history, John is believed to have used a number of sources, some of which are now lost: • unknown version(s) of the Anglo-Saxon Chronicle, possibly in Latin translation. John may have shared a lost source with William of Malmesbury, whose Gesta Regum Anglorum ("Deeds of the Kings of the English") includes similar material not found in other works. • Bede, Historia Ecclesiastica ("Ecclesiastical History") up to 731 • Asser, Vita Ælfredi ("Life of Alfred") • Hagiographical works on 10th and 11th-century saints • Lives of St Dunstan (by author "B"), Adelard and Osbern • Byrhtferth, Life of St. Oswald • Osbern of Canterbury, Life of St Ælfheah • Eadmer of Canterbury, Historia Novorum (1066–1122) • Accounts by contemporaries and local knowledge
