THAUMA´CIA(Θαυμακία: Eth. Θαυμακιεύς), a town of Magnesia in Thessaly, one of the four cities whose ships in the Trojan War were commanded by Philoctetes. It was said to have been founded by Thaumacus, the son of Poeas. Leake supposes it to be represented by the paleókastro of Askíti, one of the villages on the Magnesian coast. This Thaumacia must not be confounded with Thaumaci in Phthiotis mentioned above. (Horn. Il. 2.716; Strab. 9. p. 436; Steph. B. s. v.;Eustath. ad Hom. p. 329. 6; Plin. Nat. 4.9. s. 16; Leake, Northern Greece, vol. 4. p. 416.)
