Cierium

[4] According to Thucydides, the Boeotians had occupied the territory of Boeotia when, sixty years after the Trojan War, they had been expelled from the city of Arne by the Thessalians.

Archemachus of Euboea and other authors add that only a few Boeotians decided to stay in Arne and remain as servants of the Thessalians and were called penestae.

The territory of Cierium adjoined that of Metropolis; and we learn from an inscription cited by Leake that the adjustment of their boundaries was a frequent subject of discussion between the two people.

Pausanias also appears to speak of this temple of Athena Itonia, since he describes it as situated between Pherae and Larissa, which is sufficient to indicate the site of Cierium.

[4] Cierium is not mentioned under this name in history; but it occurs under the form Pierium, which is undoubtedly only another appellation of the same place, π and κ being, according to Smith, often interchangeable.
