Was St. Paul really on a horse? Or is just the depiction in art?
My comment above was that no horse was mentioned in Scripture. However, bunkerhill7 has made a good case that, although the noun for “horse” is not used in the Greek text, the verbs and the rest of the context make the horse pretty probable.
My other point was that this episode did not involve “seeing God” in the visual sense, but only the light and the voice. Later, however, Jesus appeared to St. Paul (and others) in dreams.
