Calocaerus
Calocaerus (died 334) was a Roman usurper against Emperor Constantine I.
Calocaerus was Magister pecoris camelorum ("Lord of the sheep and camels") in Cyprus. In 333–334 he revolted, proclaiming himself Emperor. Constantine sent his half-brother, the Censor Flavius Dalmatius to quell the rebellion, and Calocaerus was defeated, and afterwards brought to Tarsus in Cilicia, where he was tried and executed.
