An illuminator of uncertain origin, who decorated a manuscript of the works of Julius Caesar and is therefore known to art historians as the 'Caesar Master', was the artist of this Book of Hours. Several manuscripts decorated by the artist have been identified: they allow us to deduce that he worked in the middle decades of the 15th century, for clients associated mainly with London and Oxford. An inscription suggests that by 1475 this manuscript was owned by John Alburgh (probably from Alburgh, between Harleston in Norfolk, and Bungay in Suffolk) or one of his close friends or relations. Continuing the very unusual series of scenes is this representation of the Entry into Jerusalem. Christ rides on the ass, Sts. Peter and John the Evangelist follow behind, a man has climbed a tree to pick palm fronds, and townspeople watch from the city walls.
