. The hydraulic organ is often confused with the hydraulis. The hydraulis is the name of a Greek instrument created by Ctesibius of Alexandria. The hydraulis has a reservoir of air which is inserted into a cistern of water. The air is pushed into the reservoir with hand pumps, and exits the reservoir as pressurized air to blow through the pipes. The reservoir is open on the bottom, allowing water to maintain the pressure on the air as the air supply fluctuates from either the pumps pushing more air in, or the pipes letting air out. On the water organ, since the 15th century, the water is also used as a source of power to drive a mechanism similar to that of the barrel organ, which has a pinned barrel that contains a specific song to be played. The hydraulis in ancient Greek is often imagined as an automatic organ, but there is no source evidence for it.

scientist Ctesibius of Alexandria, an engineer of the 3rd century BCE. The hydraulis was the world's first keyboard instrument and was the predecessor of the modern church organ. Unlike the instrument of the Renaissance period, which is the main subject of the article on the pipe organ, the ancient hydraulis was played by hand, not automatically by the water-flow; the keys were balanced and could be played with a light touch, as is clear from the reference in a Latin poem by
Claudian Claudius Claudianus, known in English as Claudian (; c. 370 – c. 404 AD), was a Latin poet associated with the court of the Roman emperor Honorius at Mediolanum (Milan), and particularly with the general Stilicho. His work, written almost ent ...

Mechanics

Typically, water is supplied from some height above the instrument through a pipe, and air is introduced into the water stream by aspiration (using the

) into the main pipe from a side-pipe holding its top above the water source. Both water and air arrive together in the ''camera aeolis'' (wind chamber). Here, water and air separate and the compressed air is driven into a wind-trunk on top of the camera aeolis, to blow the organ pipes. Two perforated ‘splash plates’ or ‘diaphragms’ prevent water spray from getting into the organ pipes. The water, having been separated from the air, leaves the ''

'' at the same rate as it enters. It then drives a water wheel, which in turn drives the musical cylinder and the movements attached. To start the organ, the tap above the entry pipe is turned on and, given a continuous flow of water, the organ plays until the tap is closed again. Many water organs had simple water-pressure regulating devices. At the Palazzo del Quirinale, the water flows from a hilltop spring (once abundant, now only sufficient to play the organ for about 30 minutes at a time), coursing through the palace itself into a stabilizing ‘room’ some 18 metres (59 feet) above the ''camera aeolis'' in the organ grotto. This drop provides sufficient wind to power the restored six-stop instrument. Among Renaissance writers on the water organ, Salomon de Caus is particularly informative. His book of 1615 includes a short treatise on making water organs, advice on tuning and registration, and many fine engravings showing the instruments, their mechanisms and scenes in which they were used. It also includes an example of suitable music for water organ, the madrigal ''Chi farà fed' al cielo'' by Alessandro Striggio, arranged by Peter Philips.


History

Water organs were described in the numerous writings of the famous Ctesibius (3rd century BCE),
Philo of Byzantium Philo of Byzantium ( el, , ''Phílōn ho Byzántios'', ca. 280 BC – ca. 220 BC), also known as Philo Mechanicus, was a Greek engineer, physicist and writer on mechanics, who lived during the latter half of the 3rd century BC. Although he was f ...
(3rd century BCE) and Hero of Alexandria ( CE). Like the water clocks (clepsydra) of Plato's time, they were not regarded as playthings but might have had a particular significance in Greek philosophy, which made use of models and simulacra of this type. Hydraulically blown organ pipes were used to imitate birdsong, and musicologists Susi Jeans and Arthur W.J.G. Ord-Hume have suggested that it was used to create the sounds of the Vocal Memnon.Jeans, Susi and Ord-Hume, Arthur W.J.G. "Water organ". L. Macy (Ed.),

For the latter, solar heat was used to syphon water from one closed tank into another, thereby producing compressed air for sounding the pipes. Characteristics of the hydraulis have been inferred from mosaics, paintings, literary references, and partial remains. In 1931, the remains of a hydraulis were discovered in Hungary, with an inscription dating it to 228 CE. The leather and wood of the instrument had decomposed, but the surviving metal parts made it possible to reconstruct a working replica now in the Aquincum Museum in Budapest. The exact mechanism of wind production is debated, and almost nothing is known about the music played on the hydraulis, but the tone of the pipes can be studied. The Talmud mentions the instrument as not appropriate for the Jerusalem Temple. After its invention by the Greeks, the hydraulis continued to be used through antiquity in the Roman world. In the Middle Ages, Eastern Roman (Byzantine) Empire, Medieval Europe and Muslim world further developed these instruments. A well-known instance of an early positive or

By the end of the 12th century hydraulic automata were often seen in Italy and the rest of Western Europe. During the Renaissance, water organs again acquired magical and metaphysical connotations among followers of the hermetic and esoteric sciences. Organs were placed in gardens,

's illustration in '' Musurgia universalis'' (1650), long thought to be a fanciful representation of a hypothetical possibility, has been found to be accurate in every detail when compared to the organ grotto at the Quirinale, except that it was reversed left to right. There are still traces of the instrument at the Villa d'Este but the mineral-rich water of the river which cascades through the organ grotto has caused accretions which have hidden most of the evidence from view. In the early 17th century, water organs were built in England; Cornelius Drebbel built one for King James I ( Harstoffer, 1651), and Salomon de Caus built several at Richmond while in the service of Prince Henry.

and Versailles, which reached new heights of splendour and extravagance. By the end of the 17th century, however, interest in water organs had waned. As their upkeep was costly they were left to decay and were soon forgotten; by 1920 not one survived (the so-called water organ at Hellbrunn Castle, Salzburg, is a pneumatic organ driven by hydraulically operated bellows). Their mechanism was subsequently misunderstood until the Dutch engineer Van Dijk pointed out in 1954 that air was supplied to the water organ by aspiration, which was the same method used in forges and smelting works in the 16th and 17th centuries. Aspiration is the process by which air is drawn into an opening into which water flows. For the water organ, a small pipe is arranged so that one end is open to the air and the other extends into a larger pipe that contains flowing water supplied by a stream, pond or stabilizing reservoir. The longer the vertical drop of the water, the more forceful the suction will be and the greater the volume of air sucked in.


The hydraulis of Dion

In 1992, the remains of a 1st-century BCE pipe organ were found at Dion, an ancient Macedonian city near Mount Olympus, Greece, during excavations under Dimitrios Pandermalis. This instrument consisted of 24 open pipes of different height with a conical lower ending. The first 19 pipes have a height from 89 to 22 cm (35 to 8 inches). Their inner diameter gradually decreases from 2 to 1.5 cm. These 19 pipes correspond to the "''perfect system''" of the ancient Greek music which consisted of one chromatic and one diatonic scale. The pipes No. 20 to 24 are smaller and almost equal in height and they seem to form an extension of the diatonic scale. The conical end of the pipes is inserted in a metal plate. At a point just before the narrowing part of every pipe there is an opening producing the turbulence of the pressurized air and the sound. The pipes are stabilized by two metal plates. The one facing outwards has decorative motifs. The instrument had one row of keys. The lower part of the organ, with the air-pressing system, was missing. In 1995, a reconstruction project started, and by 1999 a working replica of hydraulis was made based on the archaeological finding and on ancient descriptions. The remains of the ancient hydraulis are exhibited at the
