History of the Peloponnesian War

After passing the territory of the Stratians, they proceeded through Phytia, and again through Medeon, along the borders; then through Limnaea; and so they entered the territory of the $Aegraeans, which formed no part of Acarnania, but was friendly to themselves.

Then, having reached Mount Thyamus, which is uncultivated, they proceeded across it, and so came down into the Argive country by night, and passing unobserved between the city of Argos and the Acarnanian posts at Crenae, joined the Ambraciots at Olpae.
