After absorbing the news of today, one expects to face a world consisting entirely of strikes, crimes, power failures, broken water mains, stalled trains, school shutdowns, muggers, drug addicts, neo-Nazis, and rapists.

The ancients could communicate with the gods in two ways. First, it was (and is) possible to go into a trance and visit the gods in their celestial retreats, as the great shamans have always done. More easily, and less dangerously, they could let the gods speak through code, that is, divination, using dice, entrails, bird patterns, yarrow sticks, cards.
