Apollo was worshipped as Actiacus (/ækˈtaɪ.əkəs/ ak-TY-ə-kəs; Ἄκτιακός, Aktiakos, literally "Actian"), Delphinius (/dɛlˈfɪniəs/ del-FIN-ee-əs; Δελφίνιος, Delphinios, literally "Delphic"), and Pythius (/ˈpɪθiəs/ PITH-ee-əs; Πύθιος, Puthios, from Πυθώ, Pythō, the area around Delphi), after Actium (Ἄκτιον) and Delphi (Δελφοί) respectively, two of his principal places of worship. An etiology in the Homeric hymns associated the epithet "Delphinius" with dolphins. He was worshipped as Acraephius (/əˈkriːfiəs/ ə-KREE-fee-əs; Ἀκραιφιος,[clarification needed] Akraiphios, literally "Acraephian") or Acraephiaeus (/əˌkriːfiˈiːəs/ ə-KREE-fee-EE-əs; Ἀκραιφιαίος, Akraiphiaios, literally "Acraephian") in the Boeotian town of Acraephia (Ἀκραιφία), reputedly founded by his son Acraepheus; and as Smintheus (/ˈsmɪnθjuːs/ SMIN-thews; Σμινθεύς, Smintheus, "Sminthian"—that is, "of the town of Sminthos or Sminthe") near the Troad town of Hamaxitus. The epithet "Smintheus" has historically been confused with σμίνθος, "mouse", in association with Apollo's role as a god of disease. For this he was also known as Parnopius (/pɑːrˈnoʊpiəs/ par-NOH-pee-əs; Παρνόπιος, Parnopios, from πάρνοψ, "locust") and to the Romans as Culicarius (/ˌkjuːlᵻˈkæriəs/ KEW-li-KARR-ee-əs; from Latin culicārius, "of midges").
