Dictionary of Greek and Roman Geography/Argithea
ARGI′THEA, the capital of Athamania, a district of Epirus, situated betwixt rocky mountains and deep valleys. Leake supposes that it was situated above the bridge of Koráku, to the left of the main stream of the Achelous, and that the ruins found at a small village called Knísovo are those of Argithea. (Liv. xxxviii. 1; Leake, Northern Greece, vol. iv. pp. 272, 526.)
