or Erythia, an island adjoining, according to the ancients, either to or a part of Gades; nowhere now to be found by the description given of it by ancient authors. The poets feign this to be the habitation of the fabulous Geryon, disarmed by Hercules, who drove away his cattle.

ERYTHRÆA, in Ancient Geography, a port-town of Aetolia, on the Corinthian bay. Another Erythrae of Bœotia, near Platæa and Mount Cithæron. A third Erythrae, a town of Ionia in the Hither Asia, situated in the peninsula, at its extremity, with a cognominal port. The Erythreans laid claim to the Sibyl Herochile, as their countrywoman, fumained thence Erythrea. Erythrae was famous for an ancient temple of Hercules.

ERYTHRÆA, a town of Crete, situated in the south-east of the island, at the promontory Erythreum.

ERYTHRÆUM MARE, erroneously called Rubrum by the Romans. Thus the ocean that washes Arabia and Persia, and extends a great way farther, is denominated. Hence it is, Herodotus says, that the Euphrates and Tigris fall into the Mare Erythreum. He also calls it the South Sea, on which the Persians dwell. It takes its name, not from its colour, the error of the Romans, who translated Erythreum "Rubrum;" but from Erythras, son of Perseus and Andromeda, whose kingdom lay on the confines of that sea; whence its name Erythreum.
