"Instead of calling Athena the goddess of war, wisdom, and macrame, then, we should say war and technology. And here again we have the problem of an overlap with the jurisdiction of Ares, who’s supposed to be the god of war. And let’s just say that Ares is a complete asshole. His personal aides are Fear and Terror and sometimes Strife. He is constantly at odds with Athena even though—maybe because —they are nominally the god and goddess of the same thing—war. Heracles, who is one of Athena’s human proteges, physically wounds Ares on two occasions, and even strips him of his weapons at one point! You see the fascinating thing about Ares is that he’s completely incompetent. He’s chained up by a couple of giants and imprisoned in a bronze vessel for thirteen months. He’s wounded by one of Odysseus’s drinking buddies during the Iliad . Athena knocks him out with a rock at one point. When he’s not making a complete idiot of himself in battle, he’s screwing every human female he can get his hands on, and—get this—his sons are all what we would today call serial killers. And so it seems very clear to me that Ares really was a god of war as such an entity would be recognized by people who were involved in wars all the time, and had a really clear idea of just how stupid and ugly wars are.
