The sailor who re-discovered them said that the chief desire of the people was to know whether the Moors still held Spain (Gaffarel, "Iles Fantastiques," p. 3). In a copy of "Ptolemy" addressed to Pope Urban VI. about 1380, before the alleged visit of the Portuguese, it was stated of the people at Antillia that they lived in a Christian manner, and were most prosperous, "Hie populus christianissime vivit, omnibus divitiis seculi hujus plenus" (D'Avezac, "Nouvelles Annales des voyages," 1845, II. p. 55). It was afterwards held by some that the island of Antillia was identical with St. Michael in the Azores, where a certain cluster of stone huts still bears the name of Seven Cities, and the same name is associated with a small lake by which they stand. (Humboldt's "Examen Critique," Paris, 1837, II. p. 203; Gaffarel, "Iles Fantastiques," p. 3.) XVI. HARALD THE VIKING The tales of the Norse explorations of America are now accessible in many forms, the most convenient of these being in the edition of E. L. Slafter, published by the Prince Society. As to the habits of the Vikings, the most accessible authorities are "The Age of the Vikings," by Du Chaillu, and "The Sea Kings of Norway," by Laing. The writings of the late Professor E. N. Horsford are well known, but his opinions are not yet generally accepted by students. His last work, "Leif's House in Vineland," with his daughter's supplementary essay on "Graves of the Northmen," is probably the most interesting of the series (Boston, 1893). In Longfellow's "Saga of King Olaf" (II.), included in "Tales of a Wayside Inn," there is a description of the athletic sports practised by the Vikings, which are moreover described with the greatest minuteness by Du Chaillu.
