History of Ilha de Fernando de Noronha

ographic record. An island, named Quaresma, looking very much like Fernando de Noronha island, appears in the Cantino planisphere. The Cantino map was composed by an anonymous Portuguese cartographer, and completed before November 1502, well before the Coelho expedition even set out. This has led to speculation that the island was discovered by a previous expedition. However there is no consensus on which expedition that might have been. The name, "Quaresma" means Lent, suggesting it must have been discovered in March or early April, which does not correspond well with the known expeditions. There is also a mysterious red island to the left of Quaresma in the Cantino map that does not fit with Fernando de Noronha island. Some have explained these anomalies away by reading quaresma as anaresma (meaning unknown, but sidesteps the Lent timing), and proposing that the red island is just an accidental inkblot.

Assuming Quaresma is indeed Fernando de Noronha, then who discovered it? One proposal is that it was discovered by a royal Portuguese mapping expedition that was sent out in May, 1501, commanded by an unknown captain (possibly André Gonçalves) and also accompanied by Amerigo Vespucci. According to Vespucci, this expedition returned to Lisbon in September 1502, just on time to influence the final composition of the Cantino map. Unfortunately, Vespucci does not report discovering this island then - indeed he is quite clear that the first time he (and his fellow sailors) saw the island was on the 1503 Coelho expedition. However, there is a letter written by an Italian saying that a ship arrived "from the land of Parrots" in Lisbon on July 22, 1502 (three months before Vespucci). This could be a stray ship from the mapping expedition that
