DUPEYRAT, JEAN BAPTISTE BARTHÉLEMY (French), "born at Paris, July 8th, 1759, made in 1804 several experiments in coining. A medal engraved by Brenet, with laureate head of Napoleon on obv. and on R. the inscription : MOYEN DE MULTIPLIER LES CARRÉS PAR DUPEYRAT PRÉSENTÉ A L'AD. DES MONNAIES . L' AN XII. "The object of these experiments was to obtain the four following advantages in the fabrication of coins and medals : 1st, Perfect similarity between all the dies produced by one original matrix; 2nd, Economy in the form of the dies; 3rd, Improvement in the dies, and 4th, A means of rendering the friction almost imperceptible. Dupeyrat presented to the National Institute the detail of his processes, with specimens of the pieces described above. A report made to the Class of Fine Arts by a special commission, on the 9th Nivôse, year XII. (31st December 1803), gives an account of the investigation which was instituted, and the Class, at the recommendation of the Committee, signified its approbation of the labours of Dupeyrat. To him we also owe the invention of the wet identic stamp, long used for the notes of the Bank of France; as well as of the dry identic stamp and the coincident identic stamp either wet or dry. Dupeyrat died in Paris on the 18th of October, 1834." Bibliography. — Edwards, The Napoleon Medals, London. 1837, p. 7.

DIOSCORIDES
DIOSCORIDES (Greek). This artist is perhaps the most famous of all the ancient Gem-engravers. Pyrgoteles was the contemporary of Alexander the Great, and Dioscorides that of Augustus ; both personify the glyptic art under their respective periods, the one in Greek, and the other in Roman, times. But whereas no specimen of the work of Pyrgoteles has come down to us in support of writers' evidence, a sufficient number of undoubtedly genuine examples of that of Dioscorides are extant to excite our ...
