First edition of a controversial work, published in response to the positions taken by the Dominican Fr. José Teixeira, supporter of D. António, Prior do Crato, who he followed until the end of his life, in exile in France, where he enjoyed the admiration and favour of Henry II and Catherine de Medicis. The last 49 pages include, with its own title page, but constituting a single typographic unit, the original edition of the “True genealogy of the kings of Portugal”, which would be published in vernacular (Castilian) five years later. Both works are dedicated to Archduke Cardinal Alberto of Austria. Copy only cropped at the head, keeping wide margins. Title page with extensive annotation and stain, passing on to the next two pages; about a third of the sheets with old annotations on the margins; two sheets with the upper outer corners burnt, without harming the text; occasional light stains on the upper margin of some leaves; rare minor wormholes. Contemporary binding, full flexible parchment, retaining the original endpapers. Regarding this work, we quote Alberto Navarro, Viscount of Trindade (Manuscritos & Livros Valiosos, Telles da Sylva, vol. II, p. 155): “Deste raríssimo livro [...] há exemplares na Nacional, na Torre do Tombo e na Ajuda; em livrarias privadas, parece-me que somente na minha”. Anselmo, 968. Monteverde, 3795. D. Manuel II Library, 241 and 243. BN (16th century), 405.
