Note 24 — Part II

In Kohl’s collection of early maps already alluded to as given in “Harv. Univ. Bull.,” Vol. III, reference is made (p. 175) to the portolano—A.D. 1426—of a Venetian hydrographer, Giacomo Giraldi, which has been preserved in the Biblioteca Marciana and which was reproduced at Venice by Ongania in 1881, also (p. 303) to the Map of America published during 1570 by Abraham Oertel—Ortell—b. 1527, d. 1598, and at p. 365 to the Map of the World by Joannes Oliva, A.D. 1613, as well as to an Atlas by Salvatore Oliva, A.D. 1620, showing both the Americas. In an article headed “The first true Maps,” to be found in “Nature” of December 15, 1904, pp. 159–161, mention is made that the oldest dated portolan is the first of Pietro Vesconte—Visconti—executed in 1311.
