Ms. missal for Carthusian use; written and illuminated at the Carthusian monastery of Porta Coeli (Cartuja de Porta Coeli), Valencia, Spain, ca. 1468.
Musical notation: 2-, 3-, and 4-line staves ruled in red ink, with square notation (on fol. 80v-95v and 100v-102).
Scribe: in a 17th century note tipped into the manuscript the scribe is named as the prior of the monastery from 1468 to 1479, Juan Palacia, but he is more likely to have been the patron of the manuscript rather than its scribe.
Artist: Joan Ceseres.
Decoration: 3 full-page miniatures, 8 historiated initials, marginal genre scenes, historiated catchwords; instructions for the illuminator are found in some margins.
