Book of Hours DB Development

Harvard's Houghton Library MS Lat 251 is a turn-of-the 15th century Parisian book.  Though the text is Use of Rome, the calendar is thoroughly Parisian.  The text is fragmentary, with both text and illuminations missing, but the calendar is complete, with 260 entries.  F.1r, below, is a good representitive of the decoration scheme, with banded foliage on the outer edge in muted colors.  Also note the unusual missing entries for January 2-4, where the Octaves of Stephen, John and the Innocents would usually be.
