The Pieres (Ancient Greek,"Πίερες") were a Thracian tribe[1] connected with the Brygi,[2] that long before the archaic period in Greece occupied the narrow strip of plain land, or low hill, between the mouths of the Peneius and the Haliacmon[3] rivers, at the foot of the great woody steeps of Mount Olympus.
The Pieres were expelled[5] by the Macedonians in the 8th century BC[6] from their original seats, and driven to the North beyond the Strymon river and Mount Pangaeus,[7] where they formed a new settlement which they named Pieris (Ancient Greek,"Πιερίς").
When this worship was introduced into Boeotia, the names of the mountains, grottos, and springs with which this poetic religion was connected, were transferred from the North to the South.
An offshoot from Olympus advances along the Pierian plain, in a North-west direction, as far as the ravine of the Haliacmon, where the mountains are separated by that chasm in the great eastern ridge of Northern Greece from the portion of it anciently called Bermius.
The road from Pella to Larissa in Thessaly passed through Pieria, and was probably the route which the consul Quintus Marcius Philippus pursued in the third and fourth years of the third Macedonian War (171 BC–168 BC).
