Bembine Tablet

The Bembine Tablet, the Bembine Table of Isis or the Mensa Isiaca (Isiac Tablet) is an elaborate tablet of bronze with enamel and silver inlay, most probably of Roman origin but imitating the ancient Egyptian style. It was named in the Renaissance after Cardinal Bembo, a celebrated antiquarian who acquired it after the 1527 sack of Rome. Thereafter it was used by antiquarians to penetrate the meaning of hieroglyphics, which were not authentically deciphered until the 19th century. Owing to these prior misconceptions, the tablet became of importance to western esoteric traditions.

The Tablet is now regarded as of Roman rather than Egyptian origin, dating to some time in the first century CE. Little is known of its subsequent history until after the sack of Rome in 1527, when Cardinal Bembo acquired it from a certain locksmith or ironworker into whose hands it had fallen. After Bembo's death in 1547, the Tablet was acquired by the Gonzaga rulers of Mantua, remaining in their museum until the capture of the city in 1630 by Ferdinand II's troops. It then passed through various hands until the French conquest of Italy in 1797. Alexandre Lenoir mentioned in 1809 that it was on exhibition in the Bibliothèque Nationale. After Napoleon's downfall it was returned to Italy to become a central exhibit in what is now the Museo Egizio at Turin, where it has remained.

The tablet was made of bronze with enamel and silver inlay, the figures cut very shallow and the contours of most of them delineated with thin silver wire. The bases on which the figures sat were covered with silver, later torn away, and these sections are left blank in the engraved reproduction above. It is an important example of ancient metallurgy, its surface being decorated with a variety of metals including silver, gold, copper-gold alloy and various base metals. One of the metals employed is black, made by alloying copper and tin with small amounts of gold and silver, and then 'pickling' it in organic acid. This black metal is possibly a variety of the "Corinthian bronze" described by Pliny and Plutarch.
