CASKET, a small box or chest, commonly used for jewels, money, papers or other objects of value. History and literature are full of references to the often disconcerting contents of these famous receptacles. The "Casket Letters" (q.v.) are one of the mysteries of history. Harpagnon's casket plays an important part in Moliere's L'Avare; Bluebeard gives his too-curious wife the keys of his caskets filled with precious stones; the contents of Sainte-Croix's casket brought about the trial and condemnation of the marquise de Brinvilliers, the poisoner. This very ancient piece of furniture was no doubt derived from the chest, which was the original wardrobe. It was an object of great value, covered with ivory, enamel or stamped leather, enriched with precious metals, or encrusted with jewels. One which belonged to St. Louis and is preserved in the Louvre is covered with enamelled shields of arms. In the i 6th and 17th centuries secret hiding-places were sometimes concealed in the lid oi. in a false bottom. In the U.S.A. the word also means coffin (q.v.). (See also Box.)
