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. The layout of this page, with a large arched miniature at the top of the page, is more typical of 'normal' Books of Hours than many other miniatures in this manuscript. The subject-mater, however, is extremely unusual, and while other elements in the volume suggest a Flemish, Dutch, or Italian background, this style of this image seems to owe its greatest debt to Parisian and Norman manuscript illumination.
