This illuminated book of hours was written in Florence in the middle of the fifteenth century and contains illuminations by Zanobi Strozzi.

The manuscript came to Wales in 1846 when it was donated to St David's College, Lampeter, by Thomas Phillips (1760-1851). In all, Thomas Phillips donated some 22,500 books to Lampeter, which, when added to the collections given and bequeathed by Bishop Burgess and the Bowdler family, made the library of the infant college the largest and most comprehensive in Wales.
