Aethicus Ister
Aethicus Ister (Aethicus Donares, Aethicus of Istria or Aethicus Ister) was the protagonist of the 7th/8th-century Cosmographia, purportedly written by a man of church Hieronymus (Jerome, but not the Church Father Jerome), who purportedly censors an even older work for producing the book as its censored version. It is a forgery from the Middle Ages. It describes the travels of Aethicus around the world, and includes descriptions of foreign peoples in usually less than favourable terms.

Criticisms
It displays a flat Earth cosmology, maybe for making sport of it. There are also numerous passages which deal directly with the legends of Alexander the Great. Heinz Löwe (1913–1991) found a striking correspondence between the letters of Aethicus and the Old Turkic script. He considers Aethicus to be of late Avar ethnicity from the Carpathian basin. Aethicus is believed by Franz Brunhölzl to have been a Scythian that lived in the region of present-day Dobrogea, Romania.
The Latin of the work is sometimes vulgar and facile, other times cryptic and opaque, owing in part to Jerome's extremely difficult vocabulary of Graecisms and Latin/Greek compounds. (See Herren, 2001). Anagram games, and etymological 'jokes' (e.g. using the verb 'monstrare' followed by the noun 'monstrum', then the verb 'demonstrare') and other ludic elements are found throughout. The Latin spelling of the work seems to suggest also that the author was a Merovingian Frank (Prinz, 1993), but the idea of "Merovingian" spellings has recently been attacked as an unreliable measure of origin. Furthermore, only one manuscript of the work appears to have been written in Tours, while the majority can be traced to centres in what is now Germany (Prinz, 1993). Jerome may have been associated with the Frankish translator of Pseudo-Methodius (Petrus Monachus). There are several passages which seem to be borrowed one way or another, suggesting perhaps a parallel relationship rather than one of dependence. Nevertheless, Jerome's knowledge of Greek (a rare feat in Western Europe at the time) may indicate an association with the Canterbury school of Archbishop Theodore in the late 7th century. See a recent article by Michael Herren (in Nova de Veteribus) on a possible Anglo-Saxon connection for Jerome. What seems clear is that Jerome was not limited to a single locale throughout his working lifetime.
