Smerdis , d. c. 528 B.C., second son of Cyrus the Great, king of Persia. He is also called Bardiya. He was assassinated by his brother
Cambyses II, who kept the murder a secret. Patizithes, the Magian custodian
of Cambyses' palace, deposed Cambyses (who was campaigning in Egypt),
put forward his own brother Guamata to impersonate Smerdis, and proclaimed
him king. After a reign of seven months the false Smerdis was overthrown
(521 B.C.) and slain. Darius I succeeded Guamata.
