The water organ or hydraulic organ (Greek: ὕδραυλις) (early types are sometimes called hydraulos, hydraulus or hydraula) is a type of pipe organ blown by air, where the power source pushing the air is derived by water from a natural source (e.g. by a waterfall) or by a manual pump. Consequently, the water organ lacks a bellows, blower, or compressor.
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.
A hydraulis is an early type of pipe organ that operated by converting the dynamic energy of water (Ancient Greek: ὕδωρ, romanized: húdōr) into air pressure to drive the pipes (Ancient Greek: αὐλός, romanized: aulós). Hence its name hydraulis, literally "water (driven) pipe (instrument)." It is attributed to the Hellenistic scientist Ctesibius of Alexandria, an engineer of the 3rd century BC. 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 (late 4th century), who uses this very phrase (magna levi detrudens murmura tactu . . . intonet, “let him thunder forth as he presses out mighty roarings with a light touch”) (Paneg. Manlio Theodoro, 320–22).
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 Bernoulli effect) 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 camera aeolis 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 was 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.
Water organs were described in the numerous writings of the famous Ctesibius (3rd century BC), Philo of Byzantium (3rd century BC) and Hero of Alexandria (c. 62 AD). 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. 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 AD. 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) and Muslim inventors developed, among other pieces, an automatic hydraulic organ (described by the Banu Musa in their 9th-century treatise Book of Ingenious Devices), a 'musical tree' at the palace of Khalif al-Muqtadir (ruled 908–32), and a long-distance hydraulic organ that could be heard from sixty miles away (described in the Arabic Sirr al-asrar and later translated into Latin by Roger Bacon). By the end of the 13th century hydraulic automata had reached 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, grottoes and conservatories of royal palaces and the mansions of rich patricians to delight onlookers not only with music but also with displays of automata – dancing figurines, wing-flapping birds and hammering cyclopes – all operated by projections on the musical cylinder. Other types of water organ were played out of sight and were used to simulate musical instruments apparently being played by statues in mythological scenes such as 'Orpheus playing the viol', 'The contest between Apollo and Marsyas' and 'Apollo and the nine Muses'.
The most famous water organ of the 16th century was at the Villa d'Este in Tivoli. Built about 1569–72 by Lucha Clericho (Luc de Clerc; completed by Claude Venard), it stood about six metres high under an arch, and was fed by a magnificent waterfall; it was described by Mario Cartaro in 1575 as playing 'madrigals and many other things'. G. M. Zappi (Annalie memorie de Tivoli, 1576) wrote: 'When somebody gives the order to play, at first one hears trumpets which play a while and then there is a consonance …. Countless gentlemen could not believe that this organ played by itself, according to the registers, with water, but they rather thought that there was somebody inside'. Besides automatically playing at least three pieces of music, it is now known that the organ was also provided with a keyboard.
Other Italian gardens with water organs were at Pratolino, near Florence (c. 1575), Isola de Belvedere, Ferrara (before 1599), Palazzo del Quirinale, Rome (built by Luca Biagi in 1598, restored 1990), Villa Aldobrandini, Frascati (1620), one of the Royal Palaces at Naples (1746), Villa Doria Pamphili, Rome (1758–9). Of these only the one at the Palazzo del Quirinale has survived. Kircher'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. There was one in Bagnigge Vale, London, the summer home of Nell Gwynn (1650–87), and Henry Winstanley (1644–1703), the designer of the Eddystone Lighthouse, is thought to have built one at his home in Saffron Walden, Essex. After the marriage of Princess Elizabeth to the Elector Palatine Prince Friedrich V, de Caus laid out for them the gardens at Heidelberg Castle which became famous for their beautiful and intricate waterworks. A water organ survives in the gardens at Heilbronn, Württemberg, and parts of one at the Wilhelmshöhe gardens in Kassel. The brothers Francini constructed waterworks and organs at Saint Germain-en-Laye 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.
In 1992, the remains of a 1st-century BC hydraulis were found at Dion, an ancient Macedonian city near Mount Olympus, Greece, during excavations under Prof. D. Pantermalis. 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 Archaeological Museum of Dion.
An alarm clock (alarm for short) is a clock that is designed to alert an individual or group of individuals at specified time. The primary function of these clocks is to awaken people from their night's sleep or short naps; they are sometimes used for other reminders as well. Most use sound; some use light or vibration. Some have sensors to identify when a person is in a light stage of sleep, in order to avoid waking someone who is deeply asleep, which causes tiredness, even if the person has had adequate sleep. To stop the sound or light, a button or handle on the clock is pressed; most clocks automatically stop the alarm if left unattended long enough. A classic analog alarm clock has an extra hand or inset dial that is used to specify the time at which to activate the alarm. Alarm clocks are also found on mobile phones, watches, and computers.
Many alarm clocks have radio receivers that can be set to start playing at specified times, and are known as clock radios. Some alarm clocks can set multiple alarms. A progressive alarm clock, can have different alarms for different times (see Next-Generation Alarms) and even play music of your choice. Most modern televisions, mobile phones and digital watches have alarm clock functions to turn on or make sounds at a specific time.Ancient Greek technology
Ancient Greek technology developed during the 5th century BC, continuing up to and including the Roman period, and beyond. Inventions that are credited to the ancient Greeks include the gear, screw, rotary mills, bronze casting techniques, water clock, water organ, torsion catapult, the use of steam to operate some experimental machines and toys, and a chart to find prime numbers. Many of these inventions occurred late in the Greek period, often inspired by the need to improve weapons and tactics in war. However, peaceful uses are shown by their early development of the watermill, a device which pointed to further exploitation on a large scale under the Romans. They developed surveying and mathematics to an advanced state, and many of their technical advances were published by philosophers, like Archimedes and Heron.Argo
In Greek mythology, Argo (; in Greek: Ἀργώ) was the ship on which Jason and the Argonauts sailed from Iolcos to Colchis to retrieve the Golden Fleece.Cornucopia
In classical antiquity, the cornucopia (from Latin cornu copiae), also called the horn of plenty, was a symbol of abundance and nourishment, commonly a large horn-shaped container overflowing with produce, flowers or nuts.Ctesibius
Ctesibius or Ktesibios or Tesibius (Greek: Κτησίβιος; fl. 285–222 BCE) was a Greek inventor and mathematician in Alexandria, Ptolemaic Egypt. He wrote the first treatises on the science of compressed air and its uses in pumps (and even in a kind of cannon). This, in combination with his work on the elasticity of air On pneumatics, earned him the title of "father of pneumatics." None of his written work has survived, including his Memorabilia, a compilation of his research that was cited by Athenaeus. Ctesibius' most commonly known invention today is a pipe organ (hydraulis), on which the invention of the piano was later based.Dion, Archaeological Museum
The Archaeological Museum of Dion (Greek: Αρχαιολογικό Μουσείο Δίου) is a museum in Dion in the Pieria regional unit of Central Macedonia, Greece.
The museum was established in 1983 to display excavations unearthed in the area from a
fortified city that once stood in its place from the 6th century BC to the 5th century AD. The artifacts of the museum were also discovered in Olympus, the archaeological site of ancient Leivithra and the wider Pieria regional unit.
The shown finds are witnesses of the history of Pieria.
The rector of the University of Thessaloniki, Georgios Sotiriadis, began with the first excavations from 1928 to 1931. The work was resumed by Georgios Bakalakis 30 years later. From 1973, under the direction of Professor Dimitrios Pandermalis, larger areas of the city were excavated. The works are still continuing under the direction of the University of Thessaloniki. The museum contains many items from when the Romans lived in the area, including statues, architectural members, votive and grave monuments, coins, and many other objects found in the necropolis and the sanctuaries and baths of the ancient city on site. The water organ, the Statue of Dionysos, Isis and Aphrodite Hypolympia and the Asklepios Daughters are displays of particular note.Dragon's teeth (mythology)
In Greek myth, dragon's teeth feature prominently in the legends of the Phoenician prince Cadmus and in Jason's quest for the Golden Fleece. In each case, the dragons are real and breathe fire. Their teeth, once planted, would grow into fully armed warriors.
Cadmus, the bringer of literacy and civilization, killed the sacred dragon that guarded the spring of Ares. The goddess Athena told him to sow the teeth, from which sprang a group of ferocious warriors called the spartoi. He threw a precious jewel into the midst of the warriors, who turned on each other in an attempt to seize the stone for themselves. The five survivors joined with Cadmus to found the city of Thebes.The classical legends of Cadmus and Jason have given rise to the phrase "to sow dragon's teeth." This is used as a metaphor to refer to doing something that has the effect of fomenting disputes.Glissando
In music, a glissando (Italian: [ɡlisˈsando]; plural: glissandi, abbreviated gliss.) is a glide from one pitch to another (Play ). It is an Italianized musical term derived from the French glisser, "to glide". In some contexts, it is distinguished from the continuous portamento. Some colloquial equivalents are slide, sweep (referring to the "discrete glissando" effects on guitar and harp, respectively), bend, smear, rip (for a loud, violent gliss to the beginning of a note), lip (in jazz terminology, when executed by changing one's embouchure on a wind instrument), plop, or falling hail (a glissando on a harp using the back of the fingernails).Harpe
The harpē (ἅρπη) was a type of sword or sickle; a sword with a sickle protrusion along one edge near the tip of the blade. The harpe is mentioned in Greek and Roman sources, and almost always in mythological contexts.
The harpe sword is most notably identified as the weapon used by Cronus to castrate and depose his father, Uranus. Alternately, that weapon is identified as a more traditional sickle or scythe. The harpe, scythe or sickle was either a flint or adamantine (diamond) blade, and was provided to Cronus by his mother, Gaia. According to an ancient myth recorded in Hesiod's Theogony, Uranus had cast his and Gaia's children, the Cyclopes and Hecatonchires, down into Tartarus. The enraged Gaia plotted Uranus' downfall. She beseeched each of her sons to rise up against Uranus but was refused by all but the youngest, Cronus. So, Gaia provided him with the weapon, and when Uranus next came to lay with Gaia, Cronus leapt up into action and castrated his father, overthrowing him and driving him away forever. Thus the blade (whether harpe, sickle or scythe) became a symbol of Cronus's power.
Perseus, a grandson of Cronus, is also regularly depicted in statues and sculpture armed with a harpe sword in his quest to slay the Gorgon, Medusa, and recover her head to use against Ceto. Perseus was provided with such a sword by his father, Zeus (Cronus' youngest son and later overthrower).
In Greek and Roman art it is variously depicted, but it seems that originally it was a khopesh-like sickle-sword. Later depictions often show it as a combination of a sword and sickle, and this odd interpretation is explicitly described in the 2nd century Leucippe and Clitophon .List of Roman gladiator types
There were many different types of gladiators in ancient Rome. Some of the first gladiators had been prisoners-of-war, and so some of the earliest types of gladiators were experienced fighters; Gauls, Samnites, and Thraeces (Thracians) used their native weapons and armor. Different gladiator types specialized in specific weapons and fighting techniques. Combatants were usually pitted against opponents with different, but more or less equivalent equipment, for the sake of a fair and balanced contest. Most gladiators only fought others from within the same school or Ludus, but sometimes specific gladiators could be requested to fight one from another Ludus.
Elite gladiators wore high-quality decorative armour for the pre-game parade (Pompa). Julius Caesar's gladiators wore silver armour, Domitian's wore golden armour and Nero's wore armour decorated with carved amber. Peacock feathers were used for plumes while tunics and loincloths had patterns in gold thread. For the fighting, functional combat armour was used; this too could be elaborately decorated. Some artistic sources, such as reliefs and mosaics, show gladiators with a various number of tassels hanging from one arm or leg. It has been speculated that they were a form of "scorecard" to show the number of fights a gladiator had won. Contests were managed by arena referees, and were fought under strict rules and etiquette.Combat was probably accompanied by music, whose tempo might have varied to match that of the combat. Typical instruments were a long straight trumpet (tuba), a large curved brass instrument (lituus), and a water organ (organum). During the Imperial period, the games might be preceded by a mimus, a form of comedy show. An image from Pompeii shows a "flute playing bear" (Ursus tibicen) and a "horn-blowing chicken" (Pullus cornicen), that may have been part of such a mimus.Necklace of Harmonia
The Necklace of Harmonia was a fabled object in Greek mythology that, according to legend, brought great misfortune to all of its wearers or owners, who were primarily queens and princesses of the ill-fated House of Thebes.Obelisk of Theodosius
The Obelisk of Theodosius (Turkish: Dikilitaş) is the Ancient Egyptian obelisk of Pharaoh Thutmose III re-erected in the Hippodrome of Constantinople (known today as At Meydanı or Sultanahmet Meydanı, in the modern city of Istanbul, Turkey) by the Roman emperor Theodosius I in the 4th century AD.Organ (music)
In music, the organ (from Greek ὄργανον organon, "organ, instrument, tool") is a keyboard instrument of one or more pipe divisions or other means for producing tones, each played with its own keyboard, played either with the hands on a keyboard or with the feet using pedals. The organ is a relatively old musical instrument, dating from the time of Ctesibius of Alexandria (285–222 BC), who invented the water organ. It was played throughout the Ancient Greek and Ancient Roman world, particularly during races and games. During the early medieval period it spread from the Byzantine Empire, where it continued to be used in secular (non-religious) and imperial court music, to Western Europe, where it gradually assumed a prominent place in the liturgy of the Catholic Church. Subsequently it re-emerged as a secular and recital instrument in the Classical music tradition.Panacea (medicine)
The panacea , named after the Greek goddess of universal remedy Panacea, is any supposed remedy that is claimed to cure all diseases like Dr. Sebi and prolong life indefinitely. It was in the past sought by alchemists as a connection to the elixir of life and the philosopher's stone, a mythical substance which would enable the transmutation of common metals into gold.
The Cahuilla people of the Colorado Desert region of California used the red sap of the elephant tree (Bursera microphylla) as a panacea.The Latin genus name of ginseng is Panax, (or "panacea") reflecting Linnean understanding that ginseng was widely used in traditional Chinese medicine as a cure-all.A panacea (or panaceum) is also a literary term to represent any solution to solve all problems related to a particular issue. The term panacea is also used in a negative way to describe the overuse of any one solution to solve many different problems especially in medicine.Salpinx
A salpinx (; plural salpinges ; Greek σαλπιγξ) was a trumpet-like instrument of the ancient Greeks.Sea organ
The Sea organ (Croatian: Morske orgulje) is an architectural sound art object located in Zadar, Croatia and an experimental musical instrument, which plays music by way of sea waves and tubes located underneath a set of large marble steps.Tommaso and Alessandro Francini
Tommaso Francini (1571–1651) and his younger brother Alessandro Francini (or Thomas Francine and Alexandre Francine in France) were Florentine hydraulics engineers and garden designers. They worked for Francesco I de' Medici, Grand Duke of Tuscany, above all at the Villa Medicea di Pratolino, whose water features Francesco de Vieri described thus in 1586: "the statues there turn about, play music, jet streams of water, are so many and such stupendous artworks in hidden places, that one who saw them all together would be in ecstasies over them."Francesco de' Medici's heir, his brother Ferdinando, was persuaded to part with the Francini brothers in 1597 by his niece Maria, married to Henri IV of France. Their first project, begun in 1598, was to provide fountains, grottoes, waterworks and, above all, water-driven automata for the series of garden terraces at Saint-Germain-en-Laye. The main feature there was a great fountain, from which water was channeled and conducted in siphon tubes to the reservoir in the vaulted area that supported the terrace. From there, through a series of secondary tubes, the water had sufficient head to operate grotto fountains and animate the elaborate automata that were a prized feature of Francini jeux d'eau. The upper grottoes on the third terrace opened from a Doric gallery and featured a dragon, a water organ and Neptune; on the next level, the Grotto of Hercules was flanked by two further grottoes; that on one side was devoted to Perseus and Andromeda, in which the delicately counterbalanced hero was made to descend from the ceiling by the hidden weight of water and slay a dragon that arose from the basin, and on the other a Grotto of Orpheus. The only trace of these features, whose high maintenance requirements cut their careers short when the court moved permanently to Fontainebleau, are in some engravings by Abraham Bosse, apparently derived from Francini drawings. The waterworks and automata at Saint-Germain-en-Laye were the most elaborate such things that had been seen in France up to that time, and Alexandre Francini's engravings of the brothers' works served to mark a distinct stage in the importation and transformation of Italian features in the creation of the French formal garden (Adams 1979:46) and far beyond: cast-iron versions of Francini's two-basin Fontaine rustique, dripping with stony icicles, were familiar features again in Victorian gardens.
Not all of Tommaso Francini's mechanisms for courtly entertainments were garden features. He was the designer of a revolving stage-set for an elaborately produced pageant, Le ballet de la délivrance de Renaud, presented in January 1617 at the Palais du Louvre; several contemporaries remarked on the impressive innovation, which was reinvented in the late nineteenth century, at the Residenztheater, Munich but no one was more impressed than the poet Giovanni Battista Marino, who was present and recreated the illusion in his directions for L'Adone with its elaborately staged intermezzi.In the reign of Louis XIII, Francini remained in the employ of the Marie de' Medici, the Queen Mother. He worked with Salomon de Brosse, engineering the aqueduct that brought water from the little river of Rungis to the gardens and his Medici Fountain and grotto in the Luxembourg Garden of her Palais de Luxembourg in Paris. Alessandro Francini engraved views of the fountains and brought out a Livre d'architecture in 1631 that featured many fantastically rusticated doorways and gates.The Francini brothers founded a dynasty of French fountain engineers; a younger Francini worked on fountains in the early stages of Versailles, especially the Grotto of Thetis (completed 1668, described by André Felibien, 1676 and demolished for the enlargement of the château 1686). Members of the Francini clan were still at work in the eighteenth century.Villa d'Este
The Villa d'Este is a 16th-century villa in Tivoli, near Rome, famous for its terraced hillside Italian Renaissance garden and especially for its profusion of fountains. It is now an Italian state museum, and is listed as a UNESCO world heritage site.
