The second map, depicting the North Atlantic, first appeared in Venice in 1558 with the account of Nicolò and Antonio Zeno’s discovery of America in 1380 by M. Caterino Zeno ('Dello scoprimento dell’ isole Frislanda, Eslanda, Engrouelanda, Estotilanda e Icaria fatto sotto il Polo artico da’ due fratelli Zeni, M. Nicolo il K. e M. Antonio, Francsco Marcolini', Venice, 1558). The two Venetian brothers, would have sailed to the north Atlantic around 1380, and even reached Nova Scotia. The narrative of the Zeno’s adventures was disputed at the time of publication and remained a source of controversy even into the 20th century.
