(Δικαίαρχος), an Aetolian, who played a conspicuous part in the Aetolian war against the Romans. He was employed on several embassies, and afterwards engaged in the service of Philip of Macedonia, who sent him out to conquer the Cyclades, and employed him with a fleet of twenty sail to carry on piracy. He appears to have been a most audacious and insolent person, for on his expedition against the Cyclades he erected altars to Ἀσέβεια and Παρανομία, wherever he landed. (Plb. 17.10, 18.37, 20.10, 22.14; Liv. 35.12; Diod. Excerpt. de Virt. et Vit. p. 572; Brandstäter, Die Geschicht. des Aetol. Landes, p. 273.)
