Note 70 — AUTHORITIES CONSULTED.

This is one of the finest existing specimens of antique bookbinding in the National Library at Paris. It is a work of the eleventh century, and encases a book of prayers in a mass of gold, jewels and enamels. The central object is sunk like a framed picture, and represents the Crucifixion, the Virgin and St. John on each side of the cross, and above it the veiled busts of Apollo and Diana; thus exhibiting the influence of the older Byzantine school, which is, indeed, visible throughout the entire design. This subject is executed on a thin sheet of gold, beaten up from behind into high relief, and chased upon its surface. A rich frame of jeweled ornament surrounds this object, portions of the decoration being further enriched with colored enamels; the angles are filled in with enameled emblems of the evangelists; the ground of the whole design enriched by threads and foliations of delicate gold wire.
