Note 22 — INTRODUCTION AND LIFE OF MAGELLAN.
Henry Edward John Stanley Stanley translation
A fuller treatise of navigation, as then practised, is contained in a book written by Francisco Faleiro, probably a brother of Ruy Faleiro, thus described by Barbosa Machado, in his Biblioteca Lusitana:—“Francisco Faleiro, who was equally well versed in astronomy and navigation, gave a clear statement of his science in those arts in the following work: Tratado de la Esfera y del Arte de Marear, con el Regimento de las Alturas. Sevilla, por Juan Cronberger, 1535. 4to.” This book is very rare; there is a copy in the Hydrographer’s office at Madrid.
