caption_attribution_description: T and O style mappa mundi (map of the known world) from the first printed version of Isidorus' Etymologiae (Kraus 13). The book was written in 623 and first printed in 1472 at Augsburg by one Günther Zainer (Guntherus Ziner), Isidor's sketch thus becoming the oldest printed map of the occident. Note: T-O-maps are typically displayed "East-up", show Jerusalem at the center and the paradise at the outmost East, balanced by the pillars of Hercules at the outmost West.
context_page_description: A T and O map or O–T or T–O map, also known as an Isidoran map, is a type of early world map that represents the physical world as first described by the 7th-century scholar Isidore of Seville in his De Natura Rerum and later his Etymologiae.
  Although not included in the original Isidorian maps, a later manuscript added the names of Noah's sons for each of the three continents.
  More detailed later maps with equivalent orientation are sometimes described as a "Beatine map" after the Beatus map because one of the earliest known representations of this sort is attributed to Beatus of Liébana, an 8th-century Spanish monk, in the prologue to his Commentary on the Apocalypse.
