Κάσιος ὄρος
Casius Mons (Κάσιος ὄρος, Strab. i. p.38, seq. xvii. pp. 758--796; Mel. 1.10, 3.8; Plin. Nat. 5.11. s. 12, 12.13; Lucan. Phars. 8.539, 10.433), the modern El. Katieh, or El. Kas, was the summit of a lofty range of sandstone hills, on the borders of Egypt and Arabia Petraea, immediately south of the Lake Sirbonis and the Mediterranean Sea. Near its summit stood a temple of Zeus-Ammon, and on its western flank was the tomb of Cn. Pompeius Magnus. The name of Mons Casius is familiar to English ears through Milton's verse. A gulf profound as that Serbonian bog, ‘Twixt Damiata and mount Casius old.
