Deipneus: Daemon of Good Meals.
In Akhaia, Deipneus gave his name to dinner. He's an obscure Spirit who rules over meals. He is known only from Athenaeus' Deipnosophistae, translating varyingly as The Dinner Experts, or the Learned Banqueters, or The Banquet of the Learned, or even The Gastronomers; the play relates a series of dinnertime conversations between a series of wealthy men. Food and the sexual interaction between men both play a central place in the story.
That said, our dear Deipneus gets a sparse mention merely that He is worshipped in Akhaia. So little is known of Him that scholars vary in calling Him a God, a Daemon, or a Hero. We just don't know.
Even so, I think it's always a good idea to give honor to the spirit who helps with Good Meals. As someone who just got all new kitchen appliances, and who is going out with a friend for dinner tonight, I certainly hope Deipneus spends plenty of time around me and mine. I'm sure our ancient forebears felt the same way.
