38°56′55″N 22°30′23″E / 38.94874°N 22.50641°E Narthacium or Narthakion (Ancient Greek: Ναρθάκιον or Ναρθάκἶον) was a city of Phthiotis in ancient Thessaly, in the neighbourhood of which Agesilaus, on his return from Asia in 394 BCE, gained a victory over the Thessalian cavalry. The Thessalians, after their defeat, took refuge on Mount Narthacium, between which and a place named Pras, Agesilaus set up a trophy. On the following day he crossed the mountains of the Achaean Phthiotis.[1][2][3][4] Narthacium is mentioned by Ptolemy.[5]
An inscription referring to Narthacium has been preserved, documented as IG (9) 2.89, dated to the year 140 BCE regarding a senatus consultum on a territorial dispute between Narthacium and Melitaea.[6]
The site of Narthacium is at a place called Limogardi (Λιμογάρδι), in the municipality of Lamia.[7][8]
