Thaumaci or Thaumacus (Ancient Greek: Θαυμακοί or Θαυμακός, romanized: Thaumakoi/Thaumakos), was a town and polis (city-state) of Phthiotis in Ancient Thessaly,[1] was situated on the pass called Coela, on the road from Thermopylae and the Maliac Gulf passing through Lamia.
At this place, says Livy, the traveller, after traversing rugged mountains and intricate valleys, comes suddenly in sight of an immense plain like a vast sea, the extremity of which is scarcely visible.
It was besieged by Philip V of Macedon in 199 BCE; but a reinforcement of Aetolians having made their way into the town, the king was obliged to abandon the siege.
[3][4][5] The modern town of Domokos occupies the site of Thaumaci,[6][7] and at this place inscriptions were found containing the ancient name.
William Martin Leake observes that "at the southern end of the town a rocky point, overtopping the other heights, commands a magnificent prospect of the immense plain watered by the Peneius and its branches.
