ERI´TIUM a town of Perrhaebia in Thessaly, appears to have been near Cyretiae, since it was taken along with the latter town by M. Baebius in B.C. 191. (Liv. 36.13.) Leake places it at Paleókastro, a village above Sykía, on the left bank of the Vúrgaris, a river of Tripolitis. In the church of St. George, which occupies the site of the ancient Cyretiae, Leake noticed an inscribed stone, on which the name of Apollodorus is followed by a word beginning ΕΡΗ, which he conjectures with much probability may be the place called Eritium by Livy. (Leake, Northern Greece, vol. iv. pp. 310, 313).
