The Greek adjective diopetes means 'fallen from Zeus' or 'fallen from heaven' — used of sacred objects believed to have descended from the sky, particularly the image of Artemis at Ephesus.
Diopetes appears in Acts 19:35, where the city clerk of Ephesus calms the riotous crowd by appealing to Ephesus as the guardian of the temple of Artemis and the image that fell from heaven. The term reveals the contrast between pagan claims of divine origin for their idols and the true Incarnation — Jesus Christ, who actually did come from heaven (John 3:13; 6:38). While Ephesus guarded a stone image of supposed heavenly origin, Paul proclaimed the One who truly descended from the Father and ascended back to the right hand of God.
