Note 201 — GOMES EANNES DE AZURARA; (continued 2)

Cadamosto's statement that Porto Santo had been found 27 years before his first voyage, has caused some to date this journey 1445, instead of 1455, reckoning from Zarco's discovery of 1418, and has led others to post-date Zarco's discovery by ten years; but the number xxv is no doubt a slip for xxxv. This is a very common form of error at this period. Thus, in the "Cabot" Map of 1544, the year of the original Cabotian discovery of North America is given as mccccxciiii, instead of mccccxcvii, by a (probable) malformation of the V, or simple inattention of the draughtsman. Also, in Grynaeus we have mccccciv for mccccliv.
