Bembo, Tablet of; or Mensa Isiaca. A brazen tablet inlaid with designs in Mosaic (now in the Museum at Turin) which once belonged to the famous Cardinal Bembo. Its origin and date are unknown. It is covered with Egyptian figures and hieroglyphics, and is supposed to have been an ornament in an ancient Temple of Isis. The learned Jesuit Kircher wrote a description of it, and Montfaucon has a chapter devoted to it. [ w.w.w.]
The only English work on the Isiac Tablet is by Dr. W. Wynn Westcott, who gives a photogravure in addition to its history, description, and occult significance.
