called ENNIA THRASYLLA by Dio Cassius, and ENNIA NAEVIA by Suetonius, was the wife of Macro and the mistress of Caligula. Her husband murdered Tiberius in order to accelerate the accession of Caligula; but this emperor, like a true tyrant, disliking to see those to whom he was under obligation, put to death Ennia and her husband. (Dion. Cass. 58.28, 59.10; Tac. Ann. 6.45; Suet. Cal. 12, 26.)
