Para rezar em tempos certos: O Livro de Horas do Museu de Angra do Heroísmo

The main objective of this study is to present the Book of Hours that is kept in the Museum of Angra do Heroísmo. It is an illuminated manuscript, practically unknown until now, which was acquired by this institution, in 1979, from a well-known antique bookseller in Lisbon. Presumably, it was illuminated at the end of the 15th century, or in the first years of the following century, keeping only eight illuminated folios. From its content, we highlight the uniqueness of some festivities in the calendar, the inclusion of small offices, such as the Hours of the Conception of the Virgin and the Hours of St. Barbara, and the presence of two illuminated folios in the Office of the Dead. The ownership marks allowed to reconstruct part of its history and to identify some of its previous owners.
