“Concerning the calendar of saints I find the good Venetian has inserted besides the usual feast of St. Mark, patron of Venice, on April 25 two more: that of his apparition and the finding of his relics on June 25 and a third feast on Jan. 31 (translation). The last two were special for the diocese of Venice (Aquileia). The calendar for Aquileia is given at the beginning of Grotefend, _op. cit._, Vol. 1, but does not quite tally with Leardo’s list of saints. Perhaps this is because Grotefend has modernized the calendar. It may be that Leardo, living perhaps elsewhere than in Venice or its diocese, put in feasts that were dear to him. Indeed, in view of your findings for latitude from the length of the days [see preceding note], Rome is the most likely place, perhaps, for the Venetian embassy. It lies nearly in lat. 42° N; if we allow for Leardo measuring the length of the days according to the apparent sunset and sunrise, this may well explain a discrepancy of the greater part of a degree.” [15]Berchet, _op. cit._, p. 7.

[21]This Latin translation of Ptolemy’s _Geography_ was begun by the Byzantine scholar Emmanuel Chrysoloras and completed by Jacopus Angelus in 1410; manuscripts of this translation were accompanied by maps, which, however, differ from the well-known maps in the Ptolemaic atlases of the late fifteenth and sixteenth centuries. The latter were the work of Dominus Nicolaus Germanus, known as Nicholas Donis. See A. E. Nordenskiöld, _Facsimile Atlas to the Early History of Cartography_, transl. by J. A. Ekelöf and Clements R. Markham, Stockholm, 1889, pp. 9-10. [22]Like the Leardo map of 1452, the map of Walsperger, 1448, reveals Ptolemaic influence in some of its names although all the topographical features are strictly medieval. The Genoese world map of 1447 in its elliptical form is the result of a more serious attempt to reconcile the Ptolemaic geography with the traditional views.
