A memnonium is a self-actuating system that generates music using solar energy. The name comes from the statue of Memnon, a famous tourist attraction in the Greco-Roman world that was said to emit sound when warmed by the morning sun. The Memnon statue inspired the design of musical automata in later periods, to which there are many historical references. Several intriguing technologies and engineering methods may be well suited for modern memnonium design efforts. However, full realization of solar thermoacoustic and thermokinetic sculpture would likely require deep collaboration between physics, music and other disciplines. In modern times, only a few simple proof-of-concept memnonia have been constructed.
