The best modern critical account in Spanish is Salvador Brau, Puerto Rico y su historia (Valencia, 1894).
San Salvador, however, claims historical precedence as the landfall of Columbus on his memorable voyage.
Cat Island was long supposed to be the island first reached by Columbus (12th October 1492) and named by him San Salvador.
Fox, identified San Salvador, on seemingly good grounds, with Samana (Atwood Cay), which lies about midway between Watling and Mariguana.
The chief difficulty is its size, for, if Samana is the true San Salvador, it must have been considerably larger then than now.
