OSÓRIO, D. Jerónimo.- DE REBVS, | EMMANVELIS REGIS LV- | SITANIÆ INVICTISSIMI VIRTVTE | ET AVSPICIO | GESTIS LIBRI | DVODECIM. | Auctore Hieronymo Osorio | EPISCOPO SYLVENSI.- Olisypone: Apud Antonium Gondisaluü, 1571.- 480, [2] p.; 31 cm.- E. Original edition of one of the most important texts by the humanist scholar D. Jerónimo Osório (1506-1580), who would become the last bishop of Silves (1564-1577) and the first of the renewed diocese of the Algarve, based in Faro (1577) -1580), of whom Montaigne claimed to be "le meilleur historien latin de nos siècles". The author says in the prologue that he read the Chronicle of D. Manuel de Damião de Góis ... with great work, vigilance and wit. The work describes all the remarkable deeds that took place during the reign of the Fortunate One, namely Vasco da Gama's journey, the discovery of Brazil, the events in India and Africa, all narrated with great historical rigor. Complete copy, with slight handling, keeping generous margins (308x212 mm). Title page a little dusty, with some restoration and four old ownership marks. At least the first section appears to have been washed and reglued. Numerous underlinings, signatures and annotations from the period, or slightly later (mostly two-handed), some marred by the slight trimming; some scratches, scribbles and even marginal drawings; occasional minor stains. Full binding of non-contemporary sheepskin, with new endpapers, blind stamped on the covers and gold tools on the spine. Anselmo, 694. Samodães, 2292. National Library (16th century), 560. D. Manuel II Library, 329.
