SACASSE´NE(Σακασσηνή, Strab, 2. p. 73, xi. pp. 509, 511, 529: Eth. Sacassani, Plin. Nat. 6.11), a province of Armenia, on the borders of Gogarene, which it separated from the Valley of the Araxes, and which extended to the river Cyrus. St. Martin ( Mém. sur l'Arménie, vol. i. pp. 143, 209, 210) identifies it with the Armenian province of Siounikh, which was governed up to the 12th century by a race of princes who traced their descent to Haig, first king of Armenia, and who in the 9th century had political relations with the Byzantine court. (Const. Porph. de Caeren. Aul. Byz. vol. 1. p. 397.) The SACAPENE of Ptolemy (Ptol. 5.13.9) appears to be the same as this province.
