>In classical times, his major function in popular religion was to keep away evil, and he was therefore called "apotropaios" ("averting evil") and "alexikakos" ("keeping off ill"). Apollo also had many epithets relating to his function as a healer. Some commonly-used examples are "paion" ("healer" or "helper") "epikourios" ("succouring"), "oulios" ("healer, baleful") and "loimios" ("of the plague"). In later writers, the word, "paion", usually spelled "Paean", becomes a mere epithet of Apollo in his capacity as a god of healing.
