Task: Question Generation
Input (English): In Apollo's role as a healer, his appellations included Acesius (/əˈsiːʒəs/ ə-SEE-zhəs; Ἀκέσιος, Akesios, from ἄκεσις, "healing"), Acestor (/əˈsɛstər/ ə-SES-tər; Ἀκέστωρ, Akestōr, literally "healer"), Paean (/ˈpiːən/ PEE-ən; Παιάν, Paiān, from παίειν, "to touch"),[citation needed] and Iatrus (/aɪˈætrəs/ eye-AT-rəs; Ἰατρός, Iātros, literally "physician"). Acesius was the epithet of Apollo worshipped in Elis, where he had a temple in the agora. The Romans referred to Apollo as Medicus (/ˈmɛdᵻkəs/ MED-i-kəs; literally "physician" in Latin) in this respect. A temple was dedicated to Apollo Medicus at Rome, probably next to the temple of Bellona.
