If the sun that morning had not been burning so warmly in the brassy sky of Phigerinadon II, and if he had not glimpsed the sugar-white and winebarrel-wide backside of Inga-Maria Calyphigia, while she bathed in the stream, he might have paid more attention to his plowing than to the burning pressures of heterosexuality and would have driven his furrow to the far side of the hill before the seductive music sounded along the road. He might never have heard it, and his life would have been very, very different.
