ERIGON(Ἐριγώυ, Strab. vii. pp. 327, 330; Ἐρείγων, Ptol. 3.13.8), the great W. branch of the river Axius, which, having its source in the Paeonian mountains, took a NE. course till its junction with the main stream at no great distance from Stobi. (Liv. 39.53.) It is now called by the Bulgarians Zrna Rjeka, and by the Turks Kutjuk Kará—Su. (Comp. Leake, Northern Greece, vol. iii. pp. 268, 275.) The geography of the basin of this river is so imperfectly known that its course cannot be traced.
