Callipedes

 "In the first two yeras of his reign Tiberius did not once set foot outside the gates of Rome; and even after that the farthest town he visited was Antium, where he occasionally spent a few days. Yet he announced from time to time that he would make a tour of the provinces and inspect the troops there; and almost every year went through the farce of chartering transport and requesting the free towns and colonies to have supplies of food and drink ready when he approached. At last he even allowed people to make vows for his safe retrun from the promised tour, which earned him the nickname of 'Callipedes'—the original Callipedes having been a comic actor, famous for his realistic imitation of a long-distance runner, in which he never moved from the same spot."
