Two original statements of Portuguese authors have been often quoted to support this tradition. The first comes from John de Barros, the Livy of Portugal (A.D. 1496-1570). "In his wish to gain a prosperous result from his efforts, the Prince devoted great industry and thought to the matter, and at great expense procured the aid of one Master Jacome[221] from Majorca, a man skilled in the art of navigation and in the making of maps and instruments, who was sent for, with certain of the Arab and Jewish mathematicians, to instruct the Portuguese officers in that science." Secondly, we have the statement of the mathematician Pedro Nuñes, that the Infant's mariners were "well taught and provided with instruments and rules of astrology and geometry which all map-makers should know."[222] On the other hand, it has been contended that there is no satisfactory evidence of the Infant's town having ever been finished, or of the Prince ever having lived there continuously, except during the last years of his life; and that our best authorities do not warrant us in believing that the settlement was even begun before the Tangier expedition. Henry's earlier charters are, with one exception, dated from other places, and his residence before 1438 seems to have been usually at Lisbon, Lagos, or Reposeira. Further, we have no right to speak of the "School," or "University," or "Academy" of Sagres; there may have been both teachers and learners, but there was nothing of an "institution for instruction" in the Prince's establishment. [Footnote 221: Jacob or James, who, according to one tradition, came to the Infant's "Court" shortly after the disaster of Tangier, in or about 1438. To this name the Viscount de Juromenha in his notes to Rackzynski, _Les Arts en Portugal_, 205, adds that of Master Peter, the cartographic artist of the Infant, who illuminated his maps in colours and adorned them with legends and pictures. The existence of this Peter rests upon a document at Batalha discovered by Juromenha. See also O. Martins, _Filhos de D. João I_, p. 73.] [Footnote 222: Wauwermans, _Henri le Navigateur et l'Academie Portugaise de Sagres_, gives little or no help towards the controverted question which he assumes as settled in his title. It is a general essay on the course of fifteenth-century exploration; its most useful portions are devoted to tracing the connections between geographical study in Portugal and the Netherlands.]
