s, in that its orientation is with the south at the top, one of the usual conventions of Muslim maps, in contrast with the Ptolemy map which has the north at the top. Fra Mauro was aware of the Ptolemy map, and commented that it was insufficient for many parts of the world:
"I do not think it derogatory to Ptolemy if I do not follow his Cosmografia, because, to have observed his meridians or parallels or degrees, it would be necessary in respect to the setting out of the known parts of this circumference, to leave out many provinces not mentioned by Ptolemy. But principally in latitude, that is from south to north, he has much 'terra incognita', because in his time it was unknown". (Text from Fra Mauro map)


He recognized however the extent of the East given by Ptolemy
Ptolemy

, thereby suppressing the central position that Jerusalem had held on previous maps:
"Jerusalem is indeed the center of the inhabited world latitudinally, though longitudinally it is somewhat to the west, but since the western portion is more thickly populated by reason of Europe, therefore Jerusalem is also the center longitudinally if we regard not empty space but the density of population". (Text from Fra Mauro map)


As was generally the case among Medieval scholars, Fra Mauro regarded the world as a sphere. However, he used the convention of describing the continents surrounded by water within the shape of a disc, but had no certainty about the size of the Earth:

"Likewise I have found various opinions regarding this circumference, but it is not possible to verify them. It is said to be 22,500 or 24,000 miglia or more, or less according to various considerations and opinions, but they are not of much authenticity, since they have not been tested". (Text from Fra Mauro map)


Although miglia is the Italian translation for miles, the modern mile was not standardized to be exactly 5,280 feet until 1592, so the intended estimation is somewhat ambiguous. Notably, the guess here only slightly underestimates the mean circumference of the Earth

 is reasonably accurate. Fra Mauro puts the following inscription by the southern tip of Africa, which he names the "Cape of Diab", describing the exploration by a ship from the East around 1420:

"Around 1420 a ship, or junk, from India crossed the Sea of India towards the Island of Men and the Island of Women, off Cape Diab, between the Green Islands

 and the shadows. It sailed for 40 days in a south-westerly direction without ever finding anything other than wind and water. According to these people themselves, the ship went some 2,000 miles ahead until - once favourable conditions came to an end - it turned round and sailed back to Cape Diab in 70 days".

"The ships called junks (lit. "Zonchi") that navigate these seas carry four masts or more, some of which can be raised or lowered, and have 40 to 60 cabins for the merchants and only one tiller. They can navigate without a compass

, one of these islands was populated exclusively by men and the other was populated exclusively by women, and the two would only meet for conjugal relations once a year.

 notes, there are many geographical facts reflected in Fra Mauro map for which it is not clear what Fra Mauro's source was, as no similar information is found in other preserved Western maps or manuscripts of the period. This situation can be at least partially explained by the fact that, besides the existing maps and manuscripts, an important source of information for his map were oral accounts from travelers - Venetians or foreigners - coming to Venice from all parts of the then-known world. The importance of such accounts is indicated by Fra Mauro himself in a number of inscriptions. An even earlier map, the De Virga world map
