But the scene impressed her sharply, and she carried away a very lively picture of it. The old Roman villa had been built about a hollow square open to the sky, and this square now formed the great hall of Bayfield. Deep galleries of two stories surrounded it, in place of the old colonnaded walk. Out of these opened the principal rooms of the house, and above them, upon a circular lantern of clear glass, was arched a painted dome. Sheathed on the outside with green weather-tinted copper, and surmounted by a gilt ball, this dome (which could be seen from the Axcester High Street when winter stripped the Bayfield elms) gave the building something of the appearance of an observatory.
