CLYSMA(Κλῦσμα), the name given by Eusebius to the Heroopolitan or western gulf of the Red Sea, through which the Israelites passed on dry land. ( Onomast. s. v. Βεελσεφών.Philostorgius ( H.E. 3.5) says that the gulf was so called from the place where it terminated; which would seem to indicate that the site of the modern Suezwas anciently occupied by a town of this name. In corroboration of this, Epiphanius ( adv. Haer. lib. 2. p. 618) mentions τὸ κάστρον τοῦ Κλύσματοςas one of the three ports of the Red Sea,—the others being Aïla or Elath, and Berenice (anciently Ezion-geber), both situated on the Elanitic gulf. (Reland. Palaest. pp. 471,472, 556.)
