In 1816, Lord Byron left his home in England and, after traveling through Belgium and Switzerland, eventually made his way to Italy, where he encountered, among other things, the Roman Colosseum. “A ruin—yet what ruin!” he wrote in the fourth canto of the long poem “Childe Harold's Pilgrimage.” It was the decay and emptiness that particularly appealed to him: the “seats crush'd,” the “walls bow'd,” and “the arena void” in which he heard the echo of his voice.
