Affair of the Diamond Necklace
Cagliostro himself stated during the trial following the Affair of the Diamond Necklace that he had been born of Christians of noble birth but abandoned as an orphan upon the island of Malta. He claimed to have travelled as a child to Medina, Mecca, and Cairo and upon return to Malta to have been admitted to the Sovereign Military Order of Malta, with whom he studied alchemy, the Kabbalah, and magic.
