which fell down from Jupiter

Boyd’s Bible Dictionary:

(father Jove). Supreme god of Greeks and Romans (Acts 14:12; 19:35).

Concise Bible Dictionary:

Supreme god of Greece and Rome, though the religious ideas of the two nations differed considerably. At Lystra the heathen inhabitants supposed Jupiter was impersonated by Barnabas, and at Ephesus they professed that the image of Diana had fallen from Jupiter, or heaven (Acts 14:12-13; Acts 19:35).
