p385 it has a capacity of 81 quinariae plus 5⁄12 plus 10⁄288. 124 Poleni endeavoured to reconcile these figures, so as to make them mathematically correct. 121 170 Since censors were chosen only every five years, and held office for but eighteen months, their duties in the intervening periods devolved upon other officials. The 25‑pipe: 5 digits plus ½ plus 1⁄12 plus 1⁄24 plus 5⁄288 in diameter; 17 digits plus ½ plus 2⁄12 plus 1⁄24 plus 7⁄288 in circumference; it has a capacity of 20 quinariae plus 4⁄12 plus 9⁄288; is not in use. For to the diameter of the 100‑pipe they add ⅔ plus 1⁄24 of a digit, and to the capacity, 10 quinariae plus ½ plus 1⁄24. Frontinus is best remembered for his statement: Just as a sextarius,76 for example, has a regular ratio to a cyathus,77 and I know very well that such an enumeration will appear not only dry but also complicated; nevertheless, I will make it — but as short as possible — that nothing may be lacking to the data of this office. With the water-men it had a diameter of 16 digits, having a capacity of 163 quinariae plus ½ plus 5⁄12, which is the measure of two 100‑pipes. In 97 CE Julius Frontinus was appointed by the Emperor Nerva to the post of water commissioner for the city of Rome. it 37 chapter 93 65 Defects are either of the sort that can be remedied without stopping the flow of the water, or such as cannot be made without diverting the flow, as, for example, those which have to be made in the channel itself. 7 Since the size and position (cf. 36) of the ajutage controlled the amount discharged, it was necessary to know If you find a mistake though, Sextus Julius Frontinus (c. 40 – 103 AD) was a prominent Roman civil engineer, author, soldier and senator of the late 1st century AD. Outside the City, Claudia and New Anio delivered each from its own channel; inside the City they were mixed together. The water-men are the men who receive the water from the State and in turn furnish it to the consumers. The work presents a history and description of the water-supply of the city of Rome, including the laws relating to its use and maintenance. Its elevation is followed by that of Virgo, then by that of Appia. 117a — Parker. 67 Very often, however, it is best to exercise a wise restraint in attending to their upkeep, since those who urge the construction or extension of the works cannot always be trusted.
