Some common epithets of Apollo as a healer are "paion" (παιών, literally "healer" or "helper") "epikourios" (ἐπικουρώ, "help"), "oulios" (οὐλή, "healed wound", also a "scar" ) and "loimios" (λοιμός, "plague"). In classical times, his strong function in popular religion was to keep away evil, and was therefore called "apotropaios" (ἀποτρέπω, "divert", "deter", "avert") and "<answer>alexikakos</answer>" (from v. ἀλέξω + n. κακόν, "defend from evil"). In later writers, the word, usually spelled "Paean", becomes a mere epithet of Apollo in his capacity as a god of healing.
