Note 660 — BOOK XXXIII. THE NATURAL HISTORY OF METALS.647

Pliny here refers both to the art of producing figures in relief on drinking vessels made of the precious metals, and also of giving them particular forms. A well-known line of Juvenal, Sat. ii. l. 96, affords a striking illustration of the depraved taste which existed in his time.—B. Lampridius also speaks of vessels of silver “defiled with representations of a most libidinous character;” and Capitolinus speaks of “phallovitroboli,” glass drinking vessels shaped like a phallus.
