Trichalkon

Atrax was a minor Thessalian polis on the south bank of the Peneios river, overshadowed politically by Larissa throughout most of its history. Its bronze coinage is rare enough that BCD Thessaly I remains the primary reference for attributing these pieces, with the collection itself having set the scholarly benchmark for the region. The trichalkon denomination places this squarely within the bronze fractional system common to Thessalian civic issues of the mid-fourth century, a period when local autonomy in the region was increasingly threatened by Macedonian expansion under Philip II.
