38.9487°N 22.5064°WNarthacium or Narthakion (grc|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] Narthacium is mentioned by Ptolemy.
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.[3]
The site of Narthacium is at a place called Limogardi (Λιμογάρδι), in the municipality of Lamia.
