According to Greek and Roman engineers and mathematicians from the 1st century BC to the 2nd century AD, such as Vitruvius, Heron of Alexandria or Iulius Pollux, the Hydraulis was invented by Ctesibius.

Ctesibius, a Greek inventor and mathematician, is said to have invented the hydraulis in the 3rd century BC in Alexandria.

Records of Ctesibius’ water organ have not survived, but Vitruvius and Heron of Alexandria provide descriptions of how to build an organum hydraulicum.

Attempts have been made to illustrate the water organ described by Vitruvius and Hero of Alexandria since the Middle Ages.
But the old descriptions are very complicated

Since the end of the 19th century there have been many archaeological finds that have confirmed the old writings and made it possible to replicate the Hydraulis
