It is very generally supposed that Justin was mistaken in understanding this to have been a statue erected to Simon Magus. This supposition rests on the fact that in the year 1574, there was dug up in the island of the Tiber a fragment of marble, with the inscription “Semoni Sanco Deo,” etc., being probably the base of a statue erected to the Sabine deity Semo Sancus. This inscription Justin is supposed to have mistaken for the one he gives above. This has always seemed to us very slight evidence on which to reject so precise a statement as Justin here makes; a statement which he would scarcely have hazarded in an apology addressed to Rome, where every person had the means of ascertaining its accuracy. If, as is supposed, he made a mistake, it must have been at once exposed, and other writers would not have so frequently repeated the story as they have done. See Burton’s Bampton Lectures, p. 374.
