This rare adjective literally means 'fallen from Zeus' and was used in the ancient world to describe objects—especially cult images—believed to have fallen from heaven as gifts from the gods. In Acts 19:35, the Ephesian town clerk uses it to describe the image of Artemis housed in her famous temple. The claim that the idol 'fell from heaven' authenticated its divine origin in pagan thinking. The term reflects ancient religious belief that certain sacred objects had supernatural, celestial origins.
