[259] Reproduced in Nordenskjöld, Periplus, 111, and labelled only "before 1481." The only name on the West African mainland is well down S.W., "India [portus?] pbīs fons."

[260] Twelfth century.

[261] A work by the same author, of 1457, is said to be at the Carthusian Monastery of Segorbe, near Valencia, but it is not yet fully identified, and is supposed by some to be the same as that just noticed.

[265] Is this an addition of the Editor to bring it up to date? The reviser must, however, have added very largely to this map; e. g., both Russia and Turkey (?), as here depicted, do not correspond at all to the late thirteenth century, but agree better with the fifteenth; though for 1436 Russia seems unduly magnified. Imperium Tartarorum appears immediately north of the Sea of Azov. The Moslem prince near the Bosphorus is probably meant for the Ottoman Sultan.
