[Footnote 257: The Soleri of 1380 gives twenty Atlantic islands; nineteen appear in the Soleri of 1385 (some legendary). In neither is any addition made to earlier lists.] (11) Next in order comes an anonymous Atlas of 1384 (?) in six sheets, usually called, after two of its possessors, the Pinelli-Walckenaer Portolano. It is probably a Genoese work. Its West Africa extends about as far as (or a little beyond) the Soleri of 1385, to what is apparently Cape Bojador, slightly south of the Canaries. Ten names occur beyond C. Non, among them Cavo de Sablon and Enbucder.[258] The little harbour existing to the south of Bojador seems indicated here. [Footnote 258: Bojador?] (12) And now, coming to the fifteenth century, we have first the "Combitis" Portolan of _c._ 1410--an anonymous work, but inscribed "Haec tabula ex testamento domini Nicolai de Combitis devenit in Monasterio Cartusiae florentinae." This is, in some respects, closely similar to the Vesconte of 1318. (13) Another cartographer of the early fifteenth century is Cristoforo Buondelmonte--otherwise Ensenius--whose "Description of the Cyclades" is accompanied by maps; who was the author of an important graduated chart of the North of Europe; and who also left a roughly-sketched mappemonde--perhaps a copy of a much older work--which may conceivably have been known to Prince Henry and have encouraged his explorations. This shows an Africa somewhat similar in contour to Fra Mauro's of 1457-9, but almost without names.[259] [Footnote 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." The deep indent on the middle of the W. African coast, noticed in several other maps and even in Fra Mauro, appears here on a great scale.] (14) Last among these works of the "Preparatory Time," we may take an anonymous Catalan planisphere of the early fifteenth century (in the National Library of Florence) closely resembling the great Atlas of 1375. This completes the list of important maps for the period immediately preceding the new Portuguese discoveries, and shows us the most likely examples of cartography for Prince Henry's study. Some of these he may have owned; many of them he probably inspected in person or by deputy.
