Humboldt has shown[482] that brazil-wood, being imported into Europe from the East Indies long before the discovery of America, gave its name to the country in the west where it was found in abundance, and he infers that the designation of the Atlantic island was derived from the same source. The duplication of the name, however, seems to point to a confusion of different traditions, and in the Brazil off Ireland we doubtless have an attempt to establish the mythical island of _Hy Brazil_, or _O’Brasile_, which plays a part as a vanishing island in Irish legends, although it cannot be traced to its origin. In the epic literature of Ireland relating to events of the sixth and subsequent centuries, and which was probably written down in the twelfth, there are various stories of ocean voyages, some involuntary, some voluntary, and several, like the voyage of the sons of Ua Corra about 540, of St. Brandan about 560, and of Mailduin in the eighth century, taking place in the Atlantic, and resulting in the discovery of numerous fabulous islands.[483] The name of Brazil does not appear in these early records, but it seems to belong to the same class of legends.[484] It is first mentioned, as far as I know, by William Betoner, called William of Worcester, who calls the island _Brasyle_ and _Brasylle_, and says that July 15, 1480, his brother-in-law, John Jay, began a voyage from Bristol in search of the island, returning Sept. 18 without having found it.[485] This evidently belongs to the series of voyages made by Bristol men in search of this island, which is mentioned by Pedro d’Ayala, the Spanish ambassador to England, in his famous letter of July 25, 1498, where he says that such voyages in search of _Brazylle_ and the _seven cities_ had been made for seven years past, “according to the fancies of the Genoese,” meaning Sebastian Cabot.[486] It would seem that the search for Brazil was of older date than Cabot’s arrival. He probably gave an additional impetus to the custom, adding to the stories of the fairy isles the legends of the _Sette Citade_ or _Antillia_. Hardiman,[487] quoting from a MS. history of Ireland, in the library of the Royal Irish Academy, written about 1636, mentions an “iland, which lyeth far att sea, on the west of Connaught, and some times is perceived by the inhabitants of the _Oules_ and _Iris_ ... and from Saint Helen Head. Like wise several seamen have discovered it, ... one of whom, named Captain Rich, who lives about Dublin, of late years had a view of the land, and was so neere that he discovered a harbour ... but could never make to land” because of “a mist which fell upon him.... Allsoe in many old mappes ... you still find it by the name of _O’Brasile_ under the longitude of 03°, 00´, and the latitude of 50° 20´.”[488] In 1675 a pretended account of a visit to this island was published in London, which is reprinted by Hardiman.[489]
