The first resident of note was Oebotas who was said to be the first Achaean to win at the Ancient Olympic Games. He was not honored for this and legendarily cursed others for that. Thucydides indicates it was near a great naval battle of the Peloponnesian War and that some fleeing the battle found shelter there. After the death of Alexander the Great, Dyme fell into the hands of Cassander, but his troops were driven out of the city by Aristodemus, the general of Antigonus, 314 BCE. This city had the honour, along with Patrae, of reviving the Achaean League in 280 BCE; and about this time or shortly afterwards its population received an accession from some of the inhabitants of Olenus, who abandoned their town. A battle took place at Dyme in between the Spartans under King Cleomenes III and the Achaean League under the command of Aratus of Sicyon and ended in a Spartan victory. In the Social War (220-217 BCE), the territory of Dyme, from its proximity to Elis, was frequently laid waste by the Eleans. In the First Macedonian War Cycliadas and Philip V of Macedon would prepare for an attack on Elis near Dyme; but in consequence of Dyme being the only one of the Achaean cities which espoused the cause of the Macedonian king, it was plundered by the Romans under Publius Sulpicius Galba Maximus. From this blow it never recovered; and it is said to have been without inhabitants when Pompey settled here a large number of Cilician pirates. In the civil wars which followed, some of these new inhabitants were expelled from their lands, and resumed in consequence their old occupation. Both Strabo and Pliny the Elder call Dyme a Roman colony; but this statement appears to be a mistake, since we know that Dyme was one of the towns placed under the authority of Patrae, when it was made a Roman colony by Augustus; and we are expressly told that no other Achaean town except Patrae was allowed the privilege of self-government.
