After the city Dium comes the Haliacmon River, which empties into the Thermaean Gulf. And the part after this, the seaboard of the gulf towards the north as far as the Axius River, is called Pieria, in which is the city Pydna, now called Citrum. Then come the cities Methone and Alorus. Then the Rivers Erigon and Ludias; and from1
Ludias to the city of Pella the river is navigable, a distance of one hundred and twenty stadia. Methone is forty stadia distant from Pydna and seventy stadia from Alorus. Now Pydna is a Pierian city, whereas Alorus is Bottiaean.2
Now it was in the plain before Pydna that the Romans defeated Perseus in war and destroyed the kingdom of the Macedonians, and it was in the plain before Methone that Philip the son of Amyntas, during the siege of the city, had the misfortune to have his right eye knocked out by a bolt from a catapult.
