  • Interesting fact: High-wire acts have been enjoyed since the time of the ancient Greeks and Romans. Antique medals have been excavated from Greek islands depicting men ascending inclined cords and walking across ropes stretched between cliffs. The Greeks called these high-wire performers neurobates or oribates. In the Roman city of Herculaneum there is a fresco representing an aerialist high on a rope, dancing and playing a flute. Sometimes Roman tightrope walkers stretched cables between the tops of two neighboring hills and performed comic dances and pantomimes while crossing.
