Patmos

Watson's Biblical & Theological Dictionary

a small rocky island in the AEgean Sea, about eighteen miles in circumference; which, on account of its dreary and desolate character, was used by the Roman emperors as a place of confinement for criminals. To this island St. John was banished by the Emperor Domitian; and here he had his revelation, recorded in the Apocalypse.
