Book 9
5.19
The Perrhaebi, oppressed by the Lapithae, retreated in great numbers to the mountainous country about Pindus, and to the Athamanes and Dolopes; but the Larisaei became masters of the country and of the Perrhaebi who remained there. The Larisaei lived near the Peneius, but in the neighbourhood of the Perrhaebi. They occupied the most fertile portion of the plains, except some of the very deep valleys near the lake Nessonis, into which the river, when it overflowed, usually carried away a portion of the arable ground belonging to the Larisae, who afterwards remedied this by making embankments.
