There is much historical evidence that Apollon, Artemis, and Leto were often worshipped together as a triad. In my own experience, I have found Apollon, Hermes, and Dionysos to form another triad. I was thinking about how a triad of triads centered around Apollon would form a group of seven (sacred number) gods, and who would make up the third triad. I had barely begun to consider this question when it occurred to me that a third triad could be made of Apollon with his sons Asklepios and Aristaios. I don’t currently pay cultus to Asklepios or Aristaios, though they’re occasionally on my mind, especially Aristaios. I feel like there are implications here in this triad of triads, but I haven’t fully fleshed them out. If not these two sons, who would you choose for a third triad? Thoughts about a triad of triads?
