Little of his Roman History survives, but missing portions are partly supplied from elsewhere and there are many excerpts. Enriched by anecdotes, gossip, and details of character and personal appearance, Lives of the Caesars by Suetonius born c. Besides much else, his work conveys the turmoil of his time, and the part he played in a period that saw the rise and fall of Julius Caesar in a tottering republic.
Pont du Gard De architectura is important for its descriptions of many different machines used for engineering structures, such as hoists, cranesand pulleysas well as war machines such as catapultsballistaeand siege engines. Vitruvius also described the construction of sundials and water clocksand the use of an aeolipile the first steam engine as an experiment to demonstrate the nature of atmospheric air movements wind.
Aqueducts and mills[ edit ] Books VIII, IX, and X of De architectura form the basis of much of what is known about Roman technology, now augmented Vitruvius ten books on architecture chapter archaeological studies of extant remains, such as the Pont du Gard in southern France.
Numerous such massive structures occur across the former empire, a testament to the power of Roman engineering.
Vitruvius' description of Roman aqueduct construction is short, but mentions key details especially for the way they were surveyed, and the careful choice of materials needed. His book would have been of assistance to Frontinusa general who was appointed in the late 1st century AD to administer the many aqueducts of Rome.
Frontinus wrote De aquaeductuthe definitive treatise on 1st-century Roman aqueducts, and discovered a discrepancy between the intake and supply of water caused by illegal pipes inserted into the channels to divert the water. The Roman Empire went far in exploiting water power, as the set of no fewer than 16 water mills at Barbegal in France demonstrates.
The mills ground grain in a very efficient operation, and many other mills are now known, such as the much later Hierapolis sawmill. Materials[ edit ] Vitruvius described many different construction materials used for a wide variety of different structures, as well as such details as stucco painting.
Cementconcreteand lime received in-depth descriptions, the longevity of many Roman structures being mute testimony to their skill in building materials and design.
Vitruvius advised that lead should not be used to conduct drinking water, clay pipes being preferred. He comes to this conclusion in Book VIII of De architectura after empirical observation of the apparent laborer illnesses in the plumbum foundries of his time.
Inthe United States banned the use of lead in plumbing due to lead poisoning's neurological damage. However, much of the water used by Rome and many other cities was very hard, and coated the inner surfaces of the pipes, so lead poisoning was unlikely. Design for an Archimedean water-screw Vitruvius related the famous story about Archimedes and his detection of adulterated gold in a royal crown.
When Archimedes realized the volume of the crown could be measured exactly by the displacement created in a bath of water, he ran into the street with the cry of "Eureka! He showed the crown had been alloyed with silver, and the king was defrauded.
Drainage wheel from Rio Tinto mines Sequence of drainage wheels found in Spanish mine Vitruvius described the construction of the Archimedes' screw in Chapter 10, although did not mention Archimedes by name.
It was a device widely used for raising water to irrigate fields and dewater mines. Other lifting machines mentioned in De architectura include the endless chain of buckets and the reverse overshot water-wheel.
Remains of the water wheels used for lifting water have been discovered in old mines such as those at Rio Tinto in Spain and Dolaucothi in west Wales.
The remains were discovered when these mines were reopened in modern mining attempts.
Each wheel would have been worked by a miner treading the device at the top of the wheel, by using cleats on the outer edge. That they were using such devices in mines clearly implies that they were entirely capable of using them as water wheels to develop power for a range of activities, not just for grinding wheat, but also probably for sawing timber, crushing ores, fullingand so on.
Force pump[ edit ] Ctesibius is credited with the invention of the force pumpwhich Vitruvius described as being built from bronze with valves to allow a head of water to be formed above the machine. The device is also described by Hero of Alexandria in his Pneumatica.
The machine is operated by hand in moving a lever up and down. He mentioned its use for supplying fountains above a reservoir, although a more mundane use might be as a simple fire engine.
Their functions are not described, but they are both made in bronze, just as Vitruvius specified. Vitruvius also mentioned the several automatons Ctesibius invented, and intended for amusement and pleasure rather than serving a useful function.
