Sulla now crossed the Assus, and after advancing to the foot of Mount Hedylium, encamped over against Archelaüs, who had thrown up strong entrenchments between Mounts Acontium and Hedylium, at the so-called Assian plain. The spot in which he encamped, moreover, is to this day called Archelaüs, after him. After one day’s respite, Sulla left Murena behind with one legion and two cohorts, to obstruct the enemy if they attempted to draw up their forces, while he himself held sacrifices on the banks of the Cephisus, and, when the rites were over, moved on towards Chaeroneia, to pick up the forces stationed there, and to reconnoitre Thurium, as it is called, which had been already occupied by the enemy. This is a conical-shaped hill with a craggy peak (we call it Orthopagus), and at its foot is the river Molus and a temple of Apollo Thurius. The god got this surname from Thuro, the mother of Chaeron, who was founder of Chaeroneia, according to tradition.
