=== 治癒者であり、災厄から身を守る神 ===
古典時代、民衆の宗教における主な役割は魔除けであり、そのため彼は「アポトロパイオス」(ἀποτρόπαιος、「魔除け」)、「アレクシカコス」(ἀλεξίκακος「病気を防ぐ」、v. ἀλέξω + n. κακόνから)と呼ばれていた<ref>Pausanias VIII 41, 8-IV 34, 7-Sittig. Nom P. 48. f-Aristoph. Vesp. V. 61-Paus. I 3, 4. Martin Nilsson (1967) Vol I, pp. 540, 544</ref>。アポローンはまた、癒し手としての機能に関連する多くの諡号を持っていた。よく使われる例としては、「パイオン」(παιών、文字通り「癒し手」「助け手」<ref>[https://www.perseus.tufts.edu/hopper/text?doc=Perseus:text:1999.04.0062:entry=paean-harpers]: Harper's Dictionary of classical antiquity</ref>)、「エピクーリョス」(Đπικούριος、「助ける」)、「オウリオ」(οὔλιος、「癒し手、悪意」<ref>LSJ, ou/lios、οὔλιος、shortref.</ref>)、「ロイミオ」(λοίμιος、「ペストの」)等がある。)、「ロイミオ」(λοίμιος、「ペストの」)等がある。後世の作家は、"paion"(通常 "Paean "と綴る)という言葉は、癒しの神としてのアポロンの単なる諡号になったと考えている<ref>Graf, Fritz, https://books.google.com/books?id=it9n9_I-UOkC&pg=PA66, Apollo, Taylor & Francis, 2008, isbn:978-0-203-58171-1, page66</ref>。
In classical times, his major function in popular religion was to keep away evil, and he was therefore called "apotropaios" ({{lang|grc|ἀποτρόπαιος}}, "averting evil") and "alexikakos" ({{lang|grc|ἀλεξίκακος}} "keeping off ill"; from [[verb|v.]] {{lang|grc|ἀλέξω}} + [[noun|n.]] {{lang|grc|κακόν}}). Apollo also had many epithets relating to his function as a healer. Some commonly-used examples are "paion" ({{lang|grc|παιών}} literally "healer" or "helper") "epikourios" ({{lang|grc|ἐπικούριος}}, "succouring"), "oulios" ({{lang|grc|οὔλιος}}, "healer, baleful") and "loimios" ({{lang|grc|λοίμιος}}, "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]].<ref>{{cite book|last=Graf|first=Fritz|url=https://books.google.com/books?id=it9n9_I-UOkC&pg=PA66|title=Apollo|publisher=Taylor & Francis|year=2008|isbn=978-0-203-58171-1|page=66}}</ref>
Apollo in his aspect of "healer" has a connection to the primitive god [[Paean (god)|Paean]] ({{lang|grc|Παιών-Παιήων}}), who did not have a cult of his own. Paean serves as the healer of the gods in the ''[[Iliad]]'', and seems to have originated in a pre-Greek religion.<ref>Paieon ({{lang|grc|Παιήων}}) puts pain-relieving medicines on the wounds of Pluton and Ares ( [[Iliad|Ilias]] E401).
