The court was square, and in its centre was a well; behind the bench was the wall of the house, opposite the stable; to the left a stone wall with a wicket-gate which opened on the street of the Porta Vercellina; to the right the wall of a little garden and a door always locked and leading to a separate building.

The sun had not yet risen, but gold and purple decked the place of his coming—the skyey verge above the woods, and the river, and the fields. The town still slept in twilight; only the belfry of St. Hubert glistened with a pale green light. The hush was full of great expectation. Far away on the sand-banks of the Loire the white swans were calling.
