Explain what he was saying. Please. That the image fell down from Diana??
The Greek word is diopetous, a genitive form (the nominative is diopetes--the second E is an eta). "Dio-" is from Zeus and "petes" is from the verb pipto to fall. According to Liddell and Scott's Intermediate Greek Lexicon, the word is found already in Euripides, approximately 500 years earlier.
