The Public Orations of Demosthenes, volume 2

Philip invaded Epirus, made Alexander, brother of his wife Olympias, king of the Molossi instead of Arybbas, and so secured, his own influence in that region. Arybbas was honourably received at Athens. Philip next threatened Ambracia and Leucas, which were colonies of Corinth, and promised to restore Naupactus, which was in the hands of the Achaeans, to the Aetolians. But Athens sent Demosthenes, Hegesippus, Polyeuctus and others to rouse the Corinthians to resistance, and also dispatched a force of citizens to Acarnania to help in the defence against Philip.
