A slew of Spanish Hours are coming in the near future, thanks to the detailed catalogue information in Josefina Planas’. Horae: el poder de la imagen : libros de hores en bibliotecas españolas. (Madrid: Orbis Mediaevalis, 2016). These are mostly not actually Spanish-made manuscripts, sadly, but a broad spectrum of French, Flemish, and Italian MS that are presently held in Spanish collections.
The first of these to be added is from the Biblioteca Nacional de Espagna, Vitr 23 10. This 13th C Parisian book is known as the Clinton Book of Hours, from the 15th C british owners. This manuscript starts with a long pictoral sequence, depicting two scenes of St. Edward the Confessor and then the life/death/resurrection of Jesus, leading to the calendar starting on f.29v.
The calendar itself is not graded, it uses gold and blue ink without obvious pattern. There is a tendency for lone important feasts to be gold, but when entries cluster they fall to simple alternation. Outside the main entries there are some of the Zodiac signs, 5 months, and many of the other informational notes (dates for easter and Rogation Keys). There are also several obituaries for members of the Clinton family in a later hand, in brown ink. The main entries are rather sparse, 142 dates populated, and most are the basic Parisian saints. With the exception of a row shift at the beginning of October(see f.37v below), the entries are accurate with only one incorrect entry elsewhere.
