Second editions of two of the most important texts by the great Portuguese humanist (1506-1580) who would become the last bishop of Silves (1564-1577) and the first of the renewed diocese of Algarve, in Faro (1577-1580). The first work, divided into five books, initially published in Coimbra in 1549, debates some of the major issues that concerned humanists in the second half of the 16th century; The text would achieve great success throughout Europe, having been reprinted at least 13 times during the author's lifetime. The second, initially published in Lisbon 10 years earlier, was dedicated to Infante D. Luís, fourth son of the second marriage of King D. Manuel I with D. Maria of Castile, daughter of the Catholic Monarchs; This second edition was preferred by Cardinals Bembo and Sadoleto. Both volumes feature the Medici coat of arms on the title pages. The first title page with old inscription, adding the title of the second work; some marginal notes and reading notes of the period, as well as on the endpapers. Occasional wet (tide) stains, but overall a clean, solid volume. Contemporary binding, entirely parchment, with some wear. The catalogue of the Biblioteca de D. Manuel II only mentions the first of the two works (622).
