Ares vs Mars

Are Ares and Mars the same god? In myth, yes — Ovid's Mars is caught in Vulcan's net with Venus exactly as Homer's Ares is caught by Hephaestus. In standing, no — Zeus calls Ares "most hateful to me of all gods", while Mars is the father of Romulus, has his own priests, the Salii, and the Gates of War that Rome opens in his name.
