The base attaining by a gradual slope.

Hard by, the wall, thrown backwards from the keep,

Faces the west towards th’ encircling stream,

On whose high bank continued, it enfolds

With a bold sweep an ample pasture there;

From parching northern blasts protected thus,

And so curves round to the stern keep again.

Nor does the space within the wall embraced

Stand without buildings: such there are, and good.

Two porches to two palaces belong,
