North of the Senegal-Niger are the various oases and stations of the trans-Saharan route (Tutega = Tijigja, Anzica = In-Zize, Tegaza = Taghaza, etc.) towards the Mediterranean coast. There is an unlabeled depiction of a black African man on a camel traveling from Uuegar (prob. Hoggar) to the town of Organa (ciutat organa, variously identified as Kanem or Ouargla or possibly even a misplaced depiction of Ghana - long defunct, but, on the other hand, contemporaneous with the depicted Abu Bakr). Nearby sits its Arab-looking king (Rex Organa) holding a scimitar. The River of Gold is sourced at a circular island, what seem like the Mountains of the Moon (albeit unlabeled here). From this same source also flows north the White Nile towards Egypt, which forms the frontier between the Muslim king of Nubia (Rex Onubia, his range depicted by crescent-on-gold banners) and the Christian Prester John (Preste Joha), i.e. the emperor of Ethiopia in the garb of a Christian bishop (coincidentally, this is the first visual depiction of Prester John on a portolan chart).
