It was by this road that the Gauls marched into Aetolia in 279 BCE, when they surprised and destroyed Callium, and committed the most horrible atrocities on the inhabitants.
[4] Callium also lay on the road from Pyra (the summit of Oeta, where Heracles was supposed to have burnt himself) to Naupactus, and it was divided by Mount Corax from lower Aetolia.
In the 14th and 15th centuries only the castle of Lidoriki (Velouhovo) is mentioned, possibly identified with the remains of buildings and fortifications preserved on the ancient acropolis.
Among the archaeological finds counted the fortification precinct, the sanctuaries of Demeter and Kore and possibly of Eileithyia or Artemis, the bouleuterion, the agora, the theatre and the necropolis.
On the imprints one discerns symbols of city-states, such as Chios, Lamia, Delphi, mythological creatures and profiles of male figures, recognised as prominent kings, such as Ptolemy Philopator, Attalus I, Prusias of Bithynia etc.
The entire group of sealings leads to the conclusion that Callium or at least the receiver of the documents bearing them maintained relations with the political authorities of large part of mainland Greece, of the islands as well as of the Hellenistic kingdoms.
