Aethicus Ister is the unknown author of the Cosmographia, a fictional world travelogue that probably belongs to the 7th to 8th centuries. This work, written in an abstruse Latin, makes use of a whole range of antique (the Bible, the Isidore’s Etymologies, the Pseudo-Augustine’s De mirabilibus sacrae scripturae, etc.) and medieval texts (the Apocalypse of Pseudo-Methodius, the Liber historiae Francorum, some Latin translations of the Alexander Romance, etc.). It is one of the most difficult and puzzling early medieval texts, and it has been the object of intense study since its earliest editions. According to a recent theory espoused by Herren, it could have been written c. 675–725 by a Frank with connexions to Ireland and, possibly, England.
