This passage is called Pylæ, or gates, straits, and Thermopylæ, because near the straits are hot springs, which are held in honour as sacred to Hercules. The mountain above is called Callidromus; but some writers call by the name of Callidromus the remaining part of the range extending through Ætolia and Acarnania to the Ambracian Gulf.

At Thermopylæ within the straits are strongholds, as Nicæa, on the sea of the Locri, Teichius and Heracleia above it, formerly called Trachin, founded by the Lacedæmonians. Heracleia is distant from the ancient Trachin about 6 stadia. Next follows Rhoduntia, strong by its position.
