"Tiberius took with him to Capri a number of learned Greek professors, and a picked force of soldiers, including his German bodyguard, and Thrasyllus, and a number of painted strange-looking creatures of doubtful sex and, the most curious choice of all, Cocceius Nerva. Capri is an island in the Bay of Naples about three miles from the coast. Its climate is mild in winter and cool in summer. There is only one possible landing place, the rest of the island being protected by steep cliffs and impassable thickets. How Tiberius spent his leisure time here—when he was not discussing poetry and mythology with the Greeks, or law and politics with Nerva—is too revolting a story even for history. I shall say no more than that he had brought with him a complete set of the famous books of Elephantis, the most copious encyclopædia of pornography ever gathered together. In Capri he could do what he was unable to do at Rome—practise obscenities in the open air among the trees and flowers or down at the water’s edge, and make as much noise as he liked. As some of his field-sports were extremely cruel, the sufferings of his playmates being a great part of his pleasure, he considered that the advantage of Capri’s remoteness greatly outweighed the disadvantages. He did not live wholly there: he used to go for visits to Capua, Baiæ and Antium. But Capri was his headquarters."
