Note 426 — Chapter I · (continued 3)

The editions of 1516 and 1530 have no map, and no official map was published in Spain till 1790. The Cabot map of 1544 is clearly from Spanish sources, and Brevoort is inclined to think that the single copy known is the remainder after a like suppression. The Medina sketch of 1545 is too minute to have conveyed much intelligence of the Spanish knowledge, and may have been permitted.
