The first known form of these was the late 7th or early 8th century work of Isidore of Seville. The design consists of a ring of encircling sea-ocean divided in its interior into three continents for Asia, Europe, and Africa, understood as a capital letter T within an O. It is also known as an Isidoran map or a "T and O map" or "O–T map" or "T–O map." ]]></termNote><termCreatedDate>2026-03-30 20:48:17</termCreatedDate><relation><relationType>UF</relationType><termId>31486033</termId><termName>T and O map</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31486034</termId><termName>T-O map</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31486031</termId><termName>Isidoran map</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31486032</termId><termName>O-T map</termName><termType>ND</termType></relation><relation><relationType>BT</relationType><termId>31402707</termId><termName>world maps</termName><termType>PT</termType></relation><relation><relationType>BT</relationType><termId>31361231</termId><termName>early maps</termName><termType>PT</termType></relation></term>  </Zthes>
