The martyrdom of St. Arethas, prince of Negra, and his three hundred and forty companions, is embellished in the legends of Metaphrastes and Nicephorus Callistus, copied by Baronius, (A. D 522, No. 22 - 66, A.D. 523, No. 16 - 29,) and refuted with obscure diligence, by Basnage, (Hist. des Juifs, tom. viii. l. xii. c. ii. p. 333 - 348,) who investigates the state of the Jews in Arabia and Aethiopia.
