Near the beginning of The Aeneid (29-19 BC), Aeneas is wandering around snapping twigs off trees, trying to find a decent oracle. Blood oozes out of a tree and voice says: "this is NOT a good place to build your city—be gone!" These days we have the opposite issue. The city is everywhere—we're looking for somewhere other than the city. We pick up broken bits of it and listen for the oracular voice coming from the power box or the wheelie bin. It says: "Keep going. Head towards the abandoned shopping trolley. Take the abandoned shopping trolley through the stormwater drain. When you come out the other end, there’s a patch of grass waiting for you."
