Menecrates of Syracuse

Menecrates of Syracuse (/məˈnɛkrətiːz/; Greek: Μενεκράτης ὁ Συρακούσιος) was the physician at the court of Philip of Macedon, 359—336 BC. He seems to have been a successful practitioner, but to have made himself ridiculous by calling himself Zeus, and assuming divine honours. He once wrote a letter to Philip, beginning :

He was invited one day by Philip to a magnificent entertainment, where the other guests were sumptuously fed, while he himself had nothing but incense and libations, as not being subject to the human infirmity of hunger. He was at first pleased with his reception, but afterwards, perceiving the joke and finding that no more substantial food was offered him, he left the party in disgust.
