The [[Late Bronze Age]] (from 1700 to 1200 BCE) [[Hittites|Hittite]] and [[Hurrian]] ''Aplu'' was a god of [[Plague (disease)|plague]], invoked during plague years. Here we have an [[apotrope|apotropaic]] situation, where a god originally bringing the plague was invoked to end it. Aplu, meaning ''the son of'', was a title given to the god [[Nergal]], who was linked to the Babylonian god of the sun [[Shamash]]. Homer interprets Apollo as a terrible god ({{lang|grc|δεινὸς θεός}}) who brings death and disease with his arrows, but who can also heal, possessing a magic art that separates him from the other Greek gods. In ''[[Iliad]]'', his priest prays to ''Apollo Smintheus'',<ref>"You Apollo Smintheus, let my tears become your arrows against the Danaans, for revenge".
