Sacro Catino

It was portrayed as the Holy Grail, or the simulacrum of the dish used by Jesus Christ during the Last Supper; however modern studies considered it to be an Islamic artifact of the 9th-10th century.

The source of the belief that the plate was the Holy Grail, is Jacopo da Varagine, who tells in the Genoese Chronicle that, during the first Crusade (11th century), the Genoese soldiers under the command of Guglielmo Embriaco participated in the capture of the city of Cesarea (1101), coming into possession of what was believed to be the dish of Jesus' Last Supper.

Archbishop William of Tyre wrote in the second half of the 12th century that the crusaders found the emerald plate in a temple built by Herod the Great and bought it at a high price.

In 2017, the "emerald vase" was returned to the city in its transparent color,[1] after the restoration carried out by the Opificio delle Pietre Dure in Florence.

[2] According to L. Ciatti, protagonist of the restoration attributed to Daniele Angellotto [1] In 1800, the hypothesis was advanced for the first time that it was not obtained from a huge natural emerald, but that it was a simple green glass vase, a matter with no economic value.
