Strabo refers to a water-raising machine of this kind, used to supply the garrison of the Memphite Babylon, on the Nile, and worked by 150 men. It was also used as a draining pump by the Turdetani of Iberia in the time of Strabo. This was the country of the Guadalquiver. See screw, Archimedean. Ar′chi-tecture. The classic orders are five: Doric, Ionic and Corinthian (Greek); Tuscan and Composite (Roman). The more modern is Gothic, which has several varieties: Anglo-Roman, B. C. 55 to A. D. 250; Anglo-Saxon, A. D. 800 to 1066; Anglo-Norman, 1066 to 1135; Early English or Pointed, 1135 to 1272; Pure Gothic, 1272 to 1377; Florid, 1377 to 1509; Elizabethan, 1509 to 1625. The subject is copiously and admirably treated in many excellent works. Its interest in a work of this character is not as an art, but as requiring machinery to hew and shape the stones, construct the foundations and the roof, and also calling for ingenuity in providing the building with its material acce
a, constructed in the same reign. The Romans appear to have been the first to construct arched bridges; several of which still exist in Syria and Palestine, and are the oldest stone-arch bridges in existence, unless some of the Etruscan and Chinese bridges antedate them. The Pons Senatorius was erected across the Tiber by Caius Flavius Scipio, 127 B. C. Julius Caesar's and Trajan's bridges. A trestle-bridge on piles (a. Fig. 924) was built by Julius Caesar across the Rhine about 55 B. C. He left an account of its construction, but the authorities construct it differently from the specification extant. It was founded upon piles driven into the bed of the river. The piles were united by a beam, on which were laid joists in the direction of the length of the bridge. Upon the joists were laid hurdles supporting the road-bed. An inclined fender protected the piers up stream, and each pier was stayed below by a cluster of piles. It was built in ten days.

The water was discharged into a lower reservoir, on which floated an inverted vessel suspended from a chain passing around an axis upon which the hourhand was fixed and counterbalanced. As the water rose, the vessel ascended, turning the hand on its axis and indicating the hour on a dial. Clepsydras are said to have been found in use among the Britons by Julius Caesar, 55 B. C. The Saracens had several kinds of clepsydras; one with a balance. A clock was presented by Pope Paul I. to Pepin, King of France, A. D. 760; was possibly a clepsydra. Pacificus, Archdeacon of Genoa, invented one in the ninth century. Lately, the clepsydra has been adapted by Captain Kater, for the accurate measurement of short intervals of time, by the flowing of mercury from a small orifice in the bottom of a vessel, kept constantly filled to a certain hight. The stream is inte

It was built by Ancus Martius when he united the Janiculum to the city of Rome, and is renowned as the scene of the exploit of Horatius, when Rome was attacked by Lars Porsenna of Clusium. It was still a wooden bridge in the time of Augustus, and was carried away by a flood in the time of Otho. It was situated at the foot of the Aventine mount. Caesar's bridge, over the Rhine, 55 B. C., was of wood, built upon piles (Fig. 924, a). Caesar tells us that two timbers, 18 inches square, and pointed at their lower ends, were sunk into the river, and afterward driven 2 feet distant from each other by machines; these piles were slightly inclined; two others were driven opposite to them, at a distance of 40 feet, inclining in the contrary direction; the two pairs were connected at the top by a transverse beam 2 feet thick, and over these were laid joists in the direction of the br
