The ancient Romans were the first civilization to build large, permanent bridges. Early Roman bridges used techniques introduced by Etruscan immigrants, but the Romans improved those skills, developing and enhancing methods such as arches and keystones. There were three major types of Roman bridge: wooden, pontoon, and stone. Early Roman bridges were wooden, but by the 2nd century stone was being used. Stone bridges used the arch as their basic structure, and most used concrete, the first use of this material in bridge-building.
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 Via Valeria was an ancient Roman road of Italy, the continuation north-eastwards of the Via Tiburtina from Tibur. It probably owed its origin to Marcus Valerius Messalla, censor in 154 BC.
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 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 focused 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 supplying the city of Rome. 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.
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.
The Aqua Julia is a Roman aqueduct built in 33 BC by Agrippa under Augustus to supply the city of Rome. It was repaired and expanded by Augustus from 11–4 BC.
Opus quadratum is an ancient Roman construction technique, in which squared blocks of stone of the same height were set in parallel courses, most often without the use of mortar. The Latin author Vitruvius describes the technique.
The Aqua Traiana was a 1st-century Roman aqueduct built by Emperor Trajan and inaugurated in 109 AD. It channelled water from sources around Lake Bracciano, 40 km (25 mi) north-west of Rome, to ancient Rome. It joined the earlier Aqua Alsietina to share a common lower route into Rome.
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 Sextus Julius 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.
The Aqueduct of the Gier is an ancient Roman aqueduct probably constructed in the 1st century AD to provide water for Lugdunum (Lyon), in what is now eastern France. It is the longest and best preserved of four Roman aqueducts that served the growing capital of the Roman province of Gallia Lugdunensis. It drew its water from the source of the Gier, a small tributary of the Rhone, on the slopes of Mont Pilat, 42 km (26 mi) south-west of Lyon.
Quintus Marcius Rex was a Roman politician of the Marcii Reges, a patrician family of gens Marcia, who claimed royal descent from the Roman King Ancus Marcius. He was a paternal great-grandfather of Julius Caesar.
