FRONTINUS, SEXTUS JULIUS, born of a patrician family, was prmtor of Rome A.D. 70, and about five years later was sent by Vas pasian to Britain, where be seems to have remained three years, during which he conquered the Silures. (Tacitus, 'Agricola,' 17.) About .a.n. 78 he was succeeded by Agricola in the command of the troops in Britain. On his return to Rome he wrote, under the reign of Domitian, his work, Strategematica,' iu four books, in which he gives short anecdotes of numerous Greek and Roman generals, illustrative of the practice and resources of war. Nerva entrusted him with the superintendence of the supply of water to Rome, and while filling this office, which he retained uuder Trajau, he wrote his work on the aqueducts', which has been printed in the earlier editions under the title of ' De Aquis gum in Urbem iufluunt,' hut is now generally known by the title `De Aquroductibus.' It contains much valuable informa
tion on the mode in which ancient Rome was supplied with water, and on everything that concerned this important pit of the economy of that city. Frontinus died under Train, about A.D. 106. Several other works have been attributed to him, such as De Coloniim," De Litnitibne," De Qualitate Agrorum,' but seemingly without foundation. See the llipontine edition of his works, with a life of Frontious, 8vo, 1788. ' The Stratagems, Sleightee, and Policies of Warre,' of Fron tinus wore translated Into English by Richard Morysine, and published in London in 1539, and another versos appeared in 1686, and it has been translated Into German, Italian, French, Spanish, ke. His work ' De Aquroductibus' was translated into French, and illustrated by engravings, 4to, Paris, 1530.
