In this undertaking[279] Andrea Bianco is said to have assisted, and the work was (either originally or in copy) executed for the Portuguese Government, and assisted by the same. King Affonso V supplied the draughtsmen with charts on which the recent discoveries of Prince Henry's seamen were laid down. Payment was liberal (12 to 15 sous a day to every one of the common artisans and copyists); and the Doge Francesco Foscarini, "when he witnessed the plan and the beginning of Mauro's work," trusted that Prince Henry would find therein fresh reasons for pressing on his explorations. The completed mappemonde was sent to Portugal, in charge of Stefano Trevigiano, on April 24th, 1459. This was based, perhaps, in part on the map, or maps, illustrating the voyages of Marco Polo, in the Doges' Palace in Venice, apparently on one of the walls of the Sala della Scudo. The "Polo" portions of the New Design were, however, chiefly in the Far East. In N.W. Africa, Cape Verde and Cape Rosso are marked, and near the S.W. coast of the Continent is a long inscription about the Portuguese voyages, stating that the latter "here gave new names to rivers, bays, harbours, etc., and that they made new charts, of which he (Fra Mauro) had had many in his possession." At the extreme south point of Africa is the name "Diab," with a legend telling how an Indian junk was said to have been storm-driven to this point in about 1420, and (without reaching land) to have sailed further westward for 2,000 miles during forty days. After this the Indians turned back, and after seventy days' sail, returned to Cavo di Diab, where they found on shore a huge bird's egg, as large as a barrel.[280] Fra Mauro had also himself spoken with a trustworthy person, who said that he had sailed from India past Sofala to "Garbin," a place located in the middle of the west coast of Africa close to "Dafur." "Fundan," again, a little south of Cape Rosso, may represent some Portuguese coast-name which has not elsewhere survived.
