Recalling the Acts 19 version of Saul/Paul's conversion we might be surprised of a striking parallel in 2 Maccabees 3, which tells of a man named Heliodorus, sent by a foreign king to plunder the Jerusalem temple. :
" 24 When he arrived at the treasury with his bodyguard, then and there the Sovereign of spirits and of all authority caused so great a manifestation that all who had been so bold as to accompany him were astounded by the power of God, and became faint with terror. 25 For there appeared to them a magnificently caparisoned horse, with a rider of frightening mien; it rushed furiously at Heliodorus and struck at him with its front hoofs. Its rider was seen to have armor and weapons of gold. 26 Two young men also appeared to him, remarkably strong, gloriously beautiful and splendidly dressed, who stood on either side of him and flogged him continuously, inflicting many blows on him. 27 When he suddenly fell to the ground and deep darkness came over him, his men took him up, put him on a stretcher.
Notice that in both cases a divine agent was sent ot protect his worship by blocking the passage of an enemy. And note also the mention of traveling companions who are also overcome and the main character's falling to the ground apparently weak and blind. Also in both stories the would be persecuter was assited by a pious worshiper and converted and commisioned to be a preacher to all men for this new god.
Another detail in the Acts story is the warning not to try to fight the divine calling it "kicking against the goads". In another thread It was demonstrated that Luke was apparently utilizing a motif from Greek literature, wherein the gods warn an opposer not to work against them using this very expression. Other literary links have been made specifically to Euripides' Bacchae.
