The club's copy of the Ravenna Map is based on the Ravennatis Anonymi Cosmographia ("The Cosmography of the Unknown Ravennese") which is a list of place-names covering the world from India to Ireland, compiled by an anonymous cleric in Ravenna around 700 AD. Textual evidence indicates that the author frequently used maps as his source. The surviving texts are quite challenging since the three manuscript copies are distanced from the autograph (original manuscript) by three or four generations. As a result, the copies are plagued by errors of spelling, word division, omission, and even errors of hearing. (The text was apparently dictated at one point.). The text-to-text variations are not limited to the place-names, but are also significant in the intervening commentary. Thus, the bulk of the blame cannot be placed on the original author.
