By the time the Trojan War broke out, the gods were already coming to earth less frequently than in an earlier age. Only a generation before, Zeus had fathered Sarpedon on a mortal woman. All the gods had turned up for the marriage of Peleus and Thetis. Hermes, Athena, Apollo. And it was getting harder to see them.
Every primordial age is one in which it is said that the gods have almost disappeared.
And an event referred to as being theos could easily become Zeus, the most vast and all-inclusive of gods, the god who is the background noise of the divine. Full of Zeus are the paths and the places where men meet, full of Zeus the sea and the seaports. Every one of us and in every way has need of Zeus. Indeed we are his offspring. And we also hear a great familiarity, almost a recklessness, in the way the divine is mentioned, as though to encounter divinity was hardly unusual, but rather something that could be expected, or provoked.
