Aqua Crabra refers to a Roman aqueduct supplying villas in the hinterland of the ancient town of Tusculum.
The Aqua Crabra is described by Cicero in his treatise De Lege Agraria ("On the Agrarian Law") where we learn it supplied his villa near Tusculum.
The aqueduct is also attested in the text of Frontinus.The Crabra is sometimes referred to as Aqua Mariana or Aqua Maranna del Maria.
The evidence offered by CIL VI, 1261 was interpreted by Mommsen to be connected with the Aqua Crabra, even though there is no specific mention of it in the fragmentary text.
Archaeological discoveries announced in December 2014 in conjunction with Rome's Metro C excavations have been preliminarily linked with the Aqua Crabra. This discovery consists of a large hydraulic reservoir, perhaps the largest known from the ancient city, along with a water wheel and agricultural implements.
Sextus Julius Frontinus was a prominent Roman civil engineer, author, soldier and senator of the late 1st century AD. He was a successful general under Domitian, commanding forces in Roman Britain, and on the Rhine and Danube frontiers. A novus homo, he was consul three times. Frontinus ably discharged several important administrative duties for Nerva and Trajan. However, he is best known to the post-Classical world as an author of technical treatises, especially De aquaeductu, dealing with the aqueducts of Rome.
Tusculum is a ruined Roman city in the Alban Hills, in the Latium region of Italy.
The Aniene, formerly known as the Teverone, is a 99-kilometer (62 mi) river in Lazio, Italy. It originates in the Apennines at Trevi nel Lazio and flows westward past Subiaco, Vicovaro, and Tivoli to join the Tiber in northern Rome. It formed the principal valley east of ancient Rome and became an important water source as the city's population expanded. The falls at Tivoli were noted for their beauty. Historic bridges across the river include the Ponte Nomentano, Ponte Mammolo, Ponte Salario, and Ponte di San Francesco, all of which were originally fortified with towers.
The Aqua Appia was the first Roman aqueduct, constructed in 312 BC by the co-censors Gaius Plautius Venox and Appius Claudius Caecus, the same Roman censor who also built the important Via Appia.
The Aqua Virgo was one of the eleven Roman aqueducts that supplied the city of ancient Rome. The aqueduct fell into disuse with the fall of the Western Roman Empire, but was fully restored nearly a millennium later during the Italian Renaissance to take its current form as the Acqua Vergine. The Aqua Virgo was completed in 19 BC by Marcus Agrippa, during the reign of the emperor Augustus. Its source is just before the 8th milestone north of the Via Collatina, in a marshy area about 3 km from the Via Praenestina. It was also supplemented by several feeder channels along its course. The name is thought to be derived from the purity and clarity of the water because it does not chalk significantly. According to a legend repeated by Frontinus, thirsty Roman soldiers asked a young girl for water who directed them to the springs that later supplied the aqueduct; Aqua Virgo was named after her.
The Aqua Augusta, or Serino Aqueduct, was one of the largest, most complex and costliest aqueduct systems in the Roman world; it supplied water to at least eight ancient cities in the Bay of Naples including Pompeii and Herculaneum. This aqueduct was unlike any other of its time, being a regional network rather than being focussed on one urban centre.
The Romans constructed aqueducts throughout their Republic and later Empire, to bring water from outside sources into cities and towns. Aqueduct water supplied public baths, latrines, fountains, and private households; it also supported mining operations, milling, farms, and gardens.
Aqua Anio Novus was an ancient Roman aqueduct. Like the Aqua Claudia, it was begun by emperor Caligula in 38 AD and completed in 52 AD by Claudius, who dedicated them both on August 1. Together with the Aqua Anio Vetus, Aqua Marcia and Aqua Claudia, it is regarded as one of the "four great aqueducts of Rome."
Aqua Claudia, was an ancient Roman aqueduct that, like the Aqua Anio Novus, was begun by Emperor Caligula in 38 AD and finished by Emperor Claudius in 52 AD.
Sanitation in ancient Rome was well advanced compared to other ancient cities and was providing water supply and sanitation services to residents of Rome.
The Aqua Julia or Aqua Iulia is a Roman aqueduct built in 33 BC by Agrippa. It was repaired and expanded by Augustus from 11–4 BC.
The Aqua Traiana was a 1st-century Roman aqueduct built by Emperor Trajan and inaugurated on 24 June 109 AD. It channelled water from sources around Lake Bracciano, 40 kilometers (25 mi) north-west of Rome, to Rome in ancient Roman times but had fallen into disuse by the 17th century. It fed a number of water mills on the Janiculum, including a sophisticated mill complex revealed by excavations in the 1990s under the present American Academy in Rome. Some of the Janiculum mills were famously put out of action by the Ostrogoths when they cut the aqueduct in 537 during the first siege of Rome. Belisarius restored the supply of grain by using mills floating in the Tiber. The complex of mills bears parallels with a similar complex at Barbegal in southern Gaul.
The Aqua Tepula is an ancient Roman aqueduct built in 126 BC by censors G. Servilius Caepio and L. Cassius Longinus. Its source was at the Alban hills, running only a mere 18 kilometers to Rome. The water from the Aqua Tepula, as implied in the name, was tepid and lukewarm, and thus was, as Frontinus states, not fit for human consumption.
In Ancient Rome, the Aqua Alsietina was the earlier of the two western Roman aqueducts, erected somewhere around 2BC, during the reign of emperor Augustus. It was the only water supply for the Transtiberine region.
De aquaeductu is a two-book official report given to the emperor Nerva or Trajan on the state of the aqueducts of Rome, and was written by Julius Sextus Frontinus at the end of the 1st century AD. It is also known as De Aquis or De Aqueductibus Urbis Romae. It is the earliest official report of an investigation made by a distinguished citizen on Roman engineering works to have survived. Frontinus had been appointed Water Commissioner by the emperor Nerva in AD 96.
The Aqua Marcia is one of the longest of the eleven aqueducts that supplied the city of Rome. The aqueduct was built between 144–140 BC, during the Roman Republic. The still-functioning Acqua Felice from 1586 runs on long stretches along the route of the Aqua Marcia.
An aqueduct is a watercourse constructed to carry water from a source to a distribution point far away. In modern engineering, the term aqueduct is used for any system of pipes, ditches, canals, tunnels, and other structures used for this purpose. The term aqueduct also often refers specifically to a bridge on an artificial watercourse. The word is derived from the Latin aqua ('water') and ducere. Aqueducts were used in ancient Greece, ancient Egypt, and ancient Rome. In modern times, the largest aqueducts of all have been built in the United States to supply the country's biggest cities. The simplest aqueducts are small ditches cut into the earth. Much larger channels may be used in modern aqueducts. Aqueducts sometimes run for some or all of their path through tunnels constructed underground. Modern aqueducts may also use pipelines. Historically, agricultural societies have constructed aqueducts to irrigate crops and supply large cities with drinking water.
Aqueducts or water bridges are bridges for transporting water. They are constructed to convey watercourses across gaps such as valleys or ravines. The term aqueduct may also be used to refer to the entire watercourse, as well as the bridge. Large navigable aqueducts are used as transport links for boats or ships. Aqueducts must span a crossing at the same level as the watercourses on each end. The word is derived from the Latin aqua ("water") and ducere, therefore meaning "to lead water". A modern version of an aqueduct is a pipeline bridge. They may take the form of tunnels, networks of surface channels and canals, covered clay pipes or monumental bridges.
The Aqua Anio Vetus was an ancient Roman aqueduct, and the second oldest after the Aqua Appia. It was commissioned in 272 BC and funded by treasures seized from Pyrrhus of Epirus. Its flow was more than twice that of the Aqua Appia, and it entered the city of Rome on raised arches, supplying water to higher elevations of the city.
