Ancient Roman technologyRoman technology is the collection of antiques, skills, methods, processes, and engineering practices which supported Roman civilization and made possible the expansion of the economy and military of ancient Rome (753 BC – 476 AD). The Roman Empire was one of the most technologically advanced civilizations of antiquity, with some of the more advanced concepts and inventions forgotten during the turbulent eras of Late Antiquity and the early Middle Ages.
Dolaucothi Gold MinesThe Dolaucothi Gold Mines (ˌdɔlaiˈkɔθɪ; Mwynfeydd Aur Dolaucothi) (), also known as the Ogofau Gold Mine, are ancient Roman surface and underground mines located in the valley of the River Cothi, near Pumsaint, Carmarthenshire, Wales. The gold mines are located within the Dolaucothi Estate which is now owned by the National Trust. They are the only mines for Welsh gold outside those of the Dolgellau gold-belt, and are a Scheduled Ancient Monument.
ArlesArles (ɑːrl(z), USalsoˈɑːrəl, aʁl; Arle ˈaʀle ; Classical Arelate) is a coastal city and commune in the South of France, a subprefecture in the Bouches-du-Rhône department of the Provence-Alpes-Côte d'Azur region, in the former province of Provence. A large part of the Camargue, the largest wetlands in France, is located on the territory of the commune, making it the largest commune in Metropolitan France in terms of geographic territory (in non-metropolitan France, Maripasoula (French Guiana) is much larger than Arles).
De architecturaDe architectura (On architecture, published as Ten Books on Architecture) is a treatise on architecture written by the Roman architect and military engineer Marcus Vitruvius Pollio and dedicated to his patron, the emperor Caesar Augustus, as a guide for building projects. As the only treatise on architecture to survive from antiquity, it has been regarded since the Renaissance as the first book on architectural theory, as well as a major source on the canon of classical architecture.
AusoniusDecimius Magnus Ausonius (ɔːˈsoʊniəs; 310 – c. 395) was a Roman poet and teacher of rhetoric from Burdigala, Aquitaine (now Bordeaux, France). For a time, he was tutor to the future Emperor Gratian, who afterwards bestowed the consulship on him. His best-known poems are Mosella, a description of the River Moselle, and Ephemeris, an account of a typical day in his life. His many other verses show his concern for his family, friends, teachers and circle of well-to-do acquaintances and his delight in the technical handling of meter.
Trajan's BridgeTrajan's Bridge (Podul lui Traian; Трајанов мост), also called Bridge of Apollodorus over the Danube, was a Roman segmental arch bridge, the first bridge to be built over the lower Danube and one of the greatest achievements in Roman architecture. Though it was only functional for 165 years, it is often considered to have been the longest arch bridge in both total and span length for more than 1,000 years. The bridge was constructed in 105 AD by instruction of Emperor Trajan by architect Apollodorus of Damascus, from Damascus, Roman Syria, before his Second Dacian War to allow Roman troops to cross the river.
Reverse overshot water wheelFrequently used in mines and probably elsewhere (such as agricultural drainage), the reverse overshot water wheel was a Roman innovation to help remove water from the lowest levels of underground workings. It is described by Vitruvius in his work De architectura published circa 25 BC. The remains of such systems found in Roman mines by later mining operations show that they were used in sequences so as to lift water a considerable height.
FrontinusSextus Julius Frontinus (c. 40 – 103 AD) 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.
Fire-settingFire-setting is a method of traditional mining used most commonly from prehistoric times up to the Middle Ages. Fires were set against a rock face to heat the stone, which was then doused with liquid, causing the stone to fracture by thermal shock. Some experiments have suggested that the water (or any other liquid) did not have a noticeable effect on the rock, but rather helped the miners' progress by quickly cooling down the area after the fire. This technique was best performed in opencast mines where the smoke and fumes could dissipate safely.
HushingHushing is an ancient and historic mining method using a flood or torrent of water to reveal mineral veins. The method was applied in several ways, both in prospecting for ores, and for their exploitation. Mineral veins are often hidden below soil and sub-soil, which must be stripped away to discover the ore veins. A flood of water is very effective in moving soil as well as working the ore deposits when combined with other methods such as fire-setting.
