An account of the island as seen from Arran given in O’Flaherty’s _Sketch of the Island of Arran_,[490] is quoted by H. Halliday Sterling, _Irish Minstrelsy_, p. 307 (London, 1887). Mr. Marshall, in a note in _Notes and Queries_, Sept. 22, 1883 (6th s., viii. 224), quotes Guest, _Origines Celticae_ (London, 1883), i. 126, and R. O’Flaherty, _Ogygia, sive rerum Hibernicarum chronologiae_ (London, 1685; also in English translation, Dublin, 1793), as speaking of O’Brazile. The latter work I have not seen. Mr. Marshall also quotes a familiar allusion to it by Jeremy Taylor (_Dissuasive from Popery_, 1667). This note was replied to in the same periodical, Dec. 15, 1883, by Mr. Kerslake, “N.” and W. Fraser. Fraser’s interest had been attracted by the entry of the island—much smaller than usual—on a map of the French Geographer Royal, Le Sieur Tassin, 1634-1652, and he read a paper before the Geological Society of Ireland, Jan. 20, 1870, suggesting that Brazil might be the present _Porcupine Bank_, once above water. On the same map _Rockall_ is laid down as two islands, where but a solitary rock is now known.[491] Brasil appears on the maps of the last two centuries, with _Mayda_ and _Isle Verte_, and even on the great Atlas by Jefferys, 1776, is inserted, although called “imaginary island of O’Brasil.” It grows constantly smaller, but within the second half of this century has appeared on the royal Admiralty charts as _Brazil Rock_.[492] It would be too tedious to enumerate the numerous other imaginary islands of the Atlantic to which clouds, fogs, and white caps have from time to time given rise. They are marked on all charts of the last century in profusion; mention, however, may be made of the “land of _Bus_” or _Busse_, which Frobisher’s expedition coasted along in 1576, and which has been hunted for with the lead even as late as 1821, though in vain. =F.= TOSCANELLI’S ATLANTIC OCEAN.—It has been shown elsewhere (Vol. II. pp. 30, 31, 38, 90, 101, 103) that Columbus in the main accepted the view of the width of the Atlantic, on the farther side of which Asia was supposed to be, which Toscanelli had calculated; and it has not been quite certain what actual measurement should be given to this width, but recent discoveries tend to make easier a judgment in the matter.
