Ante-Nicene Fathers Vol. IX, The Acts of Xanthippe and Polyxena…

“ In substance the Acts are a religious novel, similar in form, and to some extent in matter, to the Greek romances by Achilles Tatius, Heliodorus, and others, and based upon the belief that St. Paul actually did visit Spain, according to the intention expressed by him in Romans xv. 24. The editor of the Greek text is inclined to assign its composition to about the middle of the third century, reasoning from its relations to the Acts of Paul, and those of other apostles, which its author apparently knew and made use of. ”
