The road did not pass through the town; the grand though crumbling gate of entry lay up a short straight way to the right, and below, where the road continued down the slope, was a level of some eight miles full of trees diminishing in distance. At its further side an ample mountain, wooded, of gentle flattened outline, but high and majestic, barred the way to Rome. It was yet another of those volcanoes, fruitful after death, which are the mark of Latium: and it held hidden, as did that larger and more confused one on the rim of which I stood, a lake in its silent crater. But that lake, as I was to find, was far smaller than the glittering sea of Bolsena, whose shores now lay behind me.

When I approached Viterbo I first saw an astonishing wall, perpendicular to my road, untouched, the bones of the Middle Ages. It stood up straight before one like a range of cliffs, seeming much higher than it should; its hundred feet or so were exaggerated by the severity of its stones and by their sheer fall. For they had no ornament whatever, and few marks of decay, though many of age. Tall towers, exactly square and equally bare of carving or machicolation, stood at intervals along this forbidding defence and flanked its curtain. Then nearer by, one saw that it was not a huge castle, but the wall of
