A river separating Makedonia (Macedonia) from Thessaly.
A branch of the dreaded oath-river Styx,1 the Peneios River flowed west to east from the mountains of the central Balkan Peninsula to the Aigean Sea. Rivers flowing into the Peneios, such as the Titaressos, glided like oil across the surface of the Peneios without mixing their waters.
The Peneios River flows through a cleft in the mountains separating Mount Olympos and Mount Ossa in a region named Tempe. Before the barrier separating Tempe from the sea was breached by an earthquake, the area was dominated by marsh created by tributaries of the Peneios.
1. Styx—commonly called the "oath-river," Styx was not a river, she was an Okeanid, a daughter of Okeanos (Ocean) and Tethys,
