Roman Adjective having to do with the civilization of ancient Rome, including the kingdom, republic, and empire. This half plate revolved around a pivot passing through its thickness near the top horizontal edge, the pivot being secured in the upper ends of the braces. Aqueducts were built because the springs, wells, and Tiber River were no longer providing the safe water that was needed for the swelling urban population. Vitruvius did not invent this but was describing something already in use. A good resource for the names of arch types is. Deciding on an arbitrary length for each section, determined by the topography of the country­side, the librator then began to work his way back down the line from the water source.

The legs were fastened to the ends of the plank and also braced to it by short lengths of wood tenoned diagonally across the angle from each leg to the side of the plank. To facilitate this sighting, each glass tube had a small verti­cal bronze plate, cut with a horizontal slit, held against it by a vertical frame in which the plate could slide up and down. The librator represented another class of specialists who, operating with mechanical instru­ments and varying degrees of mechanical knowl­edge, were not required to perform real physical labor. Among other things, he has undertaken a comprehensive study of the limits of accuracy that are attainable using modern reconstructions of ancient instruments. They praise some water sources; others they really panned. Challenge them to be unique and creative in their searches.

This latter was actually a roofed and channeled stream. Homeowners who could afford running water paid for the service based on the diameter of their access pipe, a not entirely foolproof billing system. Atop this column was secured a long horizontal bronze bar or rod with a channel cut in its upper surface from one end to the other. Any practical solution must strike a balance between the water-needs of urban populations and grain producers, tax the latter's profits, and secure sufficient grain at reasonable cost for the Roman poor and the army. The Romans, always innovative, built roads on top of several of the elevated aqueducts.

The shafts were cut initially to faci­litate removal of rock during the tunneling pro­cess and also to provide the workmen with air. Trevor, Roman Aqueducts and Water Supply, Duckworth Archaeology, 2002, pp. Laws were written to deal with this, but it still went on. The population in Rome was increas­ing and, among other problems, the demand for drinking water placed a strain upon the old springs, wells, and cisterns of the community. Without changing the dioptra, the surveyor next sighted down horizontally to the second leveling rod whose disk was also adjusted now to cor­respond to the height of the dioptra sights.

It was named for its sponsor, the censor Appius Claudius Caecus, better known for another great pioneering structure of ancient Rome: the Appian Way, one of the first major Roman roads. Since the Greeks already had practical experience with this matter, it is not unlikely that the Romans acquired this knowledge from them in 312 B. Similar arrangements, though on a lesser scale, have been found in Caesarea, Venafrum and Roman-era Athens. Augustus' reign saw the building of the , and the short that supplied 's artificial lake with water for staged to entertain the populace. Some of the aqueducts are simple water channels, but many contain complex structures such as inverted siphons, tunnels, basins and drop shafts while the channels themselves can be up to 240 km in length.

In that device, called a groma, a cross-shaped frame was mounted horizontally on a vertical column. The Julian calendar was almost perfect, but it miscalculated the solar year by 11 minutes. These had two or three arcades of arches and reached prodigious heights. But with the sliding plates and the possible existence of calibrations on the plate supports it could also have been used for defining vertical angles. Thus, prompt students to convert the meter and kilometer units into feet to yield a simplified fraction with a rise of -1 foot.

The garden, farms, milling and mining operations also depended on the presence of water in aqueducts. Stone or brick ribs were Iaid on the wooden frame, the horizontal sides above the piers were constructed, and cement and rubble were filled in behind. They used formulas to calculate the arch designs. The qanaat, an underground channel with vertical shafts at intervals along its length, was well known throughout the Near East in this same century. Directing students to find as many sources as possible for their information results in a better discussion at the end. The Romans were great builders and the mighty Roman Towns needed a mighty water supply to keep the people clean and to drink.

The most recognizable feature of Roman aqueducts may be the bridges constructed using rounded stone arches. Any failure to live up to the contract could cause the forfeiture of this deposit. Originally, the Tiber River and nearby springs and wells provided sufficient water. However, the channel would have to have a gradient. Ten great aqueducts with a total length of five hundred kilometres brought enough water for the million inhabitants to use an average of one thousand litres a day each!! As simple as were the surveying instruments of the Romans, they proved more than adequate when used with care and were not substantially improved upon until the sixteenth century inventions of the plane-table, slit-and-wire sights, a separate sight rule of the form used today, and the true theodolite.

The Romans built over 50,000 miles of road by 200 A. Rome was now master of an empire. It should be understood that librators demonstrated no inten­tion of maintaining a constant gradient for the entire length of an aqueduct channel. By the early Imperial era, the city's aqueducts supported a population of over a million, and an extravagant water supply for public amenities had become a fundamental part of Roman life. This aque­duct was completed by 19 B.
