The Philippine Islands, 1493-1898, Volume 33, 1519-1522 / Explorations by early navigators, descriptions of the islands and their peoples, their history and records of the Catholic missions, as related in contemporaneous books and manuscripts, showing the political, economic, commercial and religious conditions of those islands from their earliest relations with European nations to the close of the nineteenth century

An eyewitness account by a participant of the first circumnavigation recounts a detailed shipboard journal of a multi-year expedition: its preparations, sea routes, the hazardous passage through southern straits, the long Pacific crossing, encounters with island peoples, descriptions of landscapes, flora, fauna, navigation charts and practical measures, daily life, illnesses, conflicts and losses, and the outcomes of landfalls in the Spice Islands and in archipelagos of the western Pacific. The text combines mapped sketches, ethnographic notes, and navigational data, blending travel narrative with careful recording of observations useful to later seafarers and scholars.
