Book of Hours were prayer books designed for the laity, but modeled on the Divine Office, a cycle of daily devotions, prayers and readings, performed by members of religious orders and the clergy. Its central text is the Hours of the Virgin. There are eight hours (times for prayer ): Matins, Lauds. Prime, Terce, Sext, None, Vespers and Compline. During the Middle Ages, the leaves making up a Book of Hours were written by hand on expensive parchment and beautifully illuminated with jewel-like pigments and gold leaf. These illuminated manuscripts combined the collaborative efforts of an array of highly skilled craftspeople; requiring the joint labors of the parchmenter, professional scribes to write the text in Gothic script, artists to illuminate the pages with decorations, and masterful binders to complete the process.

This tiny vellum leaf is from an early French Book of Hours. This leaf has one large illuminated initial and numerous small initials, painted in blue and red pen work with burnished gold leaf. The rubric, psalmus dauid, is in red. The text is from the famous Te Deum (also known as Ambrosian Hymn), a traditional hymn of joy and thanksgiving. Beginning with the large initial "T" on the recto, the text reads:

Te Deum laudamus: te Dominum confitemur.
Te aeternum Patrem omnis terra veneratur.
Tibi omnes Angeli; tibi Caeli et universae Potestates;
Tibi Cherubim et Seraphim incessabili voce proclamant:
Sanctus, Sanctus, Sanctus, Dominus Deus Sabaoth.
Pleni sunt caeli et terra maiestatis gloriae tuae.

This translates in English as:
We praise thee, O God: we acknowledge thee to be the Lord.
All the earth doth worship thee: the Father everlasting.
To thee all Angels cry aloud: the Heavens, and all the Powers therein.
To thee Cherubim and Seraphim: continually do cry,
Holy, Holy, Holy: Lord God of Sabaoth;
Heaven and earth are full of the Majesty: of thy glory.
