POLLIO)  , Roman architect and engineer, author of a celebrated work on architecture . Nothing is known concerning him except what can be gathered from his own writings . Owing to the discovery of inscriptions relating to the Gens Vitruvia at Formiae in Campania (Mola di Gaeta), it has been suggested that he was a native of that city, and he has been less reasonably connected with Verona on the strength of an existing arch of the 3rd century, which is inscribed with the name of a later architect of the same family name—" Lucius Vitruvius Cerdo, a freedman of Lucius." From Vitruvius himself we learn that he was appointed, in the reign of Augustus, together with three others, a superintendent of balistae and other military engines, a post which, he says, he owed to the friendly influence of the emperor's sister, probably Octavia (De Architectura, i. pref.) . In another passage (v . 1) he describes a basilica and adjacent aedes Augusti, of which hewas the architect . From viii . 3 it has been supposed that he had served in Africa in the time of Julius Caesar, probably as a military engineer, but the words hardly bear this interpretation . He speaks of himself as being low in stature, and at the time of his writing bowed down by age and ill-health (ii. pref.) . He appears to have enjoyed no great reputation as an architect, and, with philosophic contentment, records that he possessed but little fortune . Though a great student of Greek philosophy and science, he was unpractised in literature, and his style is very involved and obscure . To a great extent the theoretical and historical parts of his work are compiled from earlier Greek authors, of whom he gives a list at i. r and viii . 3 .

The

practical portions, on the contrary, are evidently the result of his own professional experience, and are written with much sagacity, and in a far clearer style than the more pedantic chapters, in which he gives the somewhat fanciful theories of the Greeks . Some sections of the latter, especially those on the connexion between music and architecture, the scale of harmonic pro-portions, and the Greek use of bronze vases to reverberate and strengthen the actors' voices in the theatre, are now almost wholly unintelligible . Vitruvius's name is mentioned by Frontinus in his work on the aqueducts of Rome; and most of what Pliny says (Hilt . Nat. xxxv. and xxxvi.) about methods of wall-painting, the preparation of the stucco surface, and other practical details in building is taken almost word for word from Vitruvius, especially from vi . 1, though without any acknowledgment of the source . The treatise De Architectura Libri Decem is dedicated to Augustus . Lost for a long time, it was rediscovered in the 15th century at St Gall; the oldest existing MS. dates from the loth century . From the early Renaissance down to a comparatively recent time the influence of this treatise has been remarkably great . Throughout the period of the classical revival Vitruvius was the chief authority studied by architects, and in every point his precepts were accepted as final . In some cases a failure to understand his meaning led to curious results; for example, the medieval custom, not uncommon in England, of placing rows of earthenware jars under the floor of the stalls in church choirs, appears to have been an attempt to follow out suggestions raised by Vitruvius as to the advantages of placing bronze vases round the auditorium of theatres . Bramante, Michelangelo, Palladio, Vignola and earlier architects were careful students of the work of Vitruvius, which through them has largely influenced the architecture of almost all European countries . Bk. i. opens with a dedication to Augustus .

The subjects of its nine chapters are—(I) the Corinthian, Ionic and Doric orders; (2) the ornaments of capitals, &c.; (3) the Doric order; (4) proportions of the cella and pronaos; (5) sites of temples; (6) doorways of temples and their architraves; (7) the Etruscan or Tuscan order of- temples; (8) circular temples; (9) altars . Bk. v., on public buildings, has a preface on the theories of Pythagoras, &c . Its twelve chapters treat—(I) of fora and basilicae, with a description of his own basilica at Fanum; (2) of the adjuncts of a forum (aerarium, prison and curia) ; (3) of theatres, their site and construction; (4) of laws of harmonics; (5) of the arrangement of tuned bronze vases in theatres for acoustic purposes; (6) of Roman theatres; (7) of Greek theatres; (8) of the selection of sites of theatres according to acoustic principles; (9) of porticus and covered walks; (io) of baths, their floors, hypocausts, the construction and use of various parts; (II) of palaestrae, xysti and other Greek buildings for the exercise of athletes; (12) ofharbours and quays .

wax, finished by friction; cc . Io-14 on artificial colours—black, blue, purple; c. to white lead and ostrum, i.e. murex purple and imitations of murex dye . ' The excavations made in 1887 have shown that Vitruvius was right in describing the great temple of Olympian Zeus at Athens as being octastyle . The previously almost universal opinion that it was decastyle had led to the needless theory that the passage containing this statement was corrupt .

(J . H . M.) The best edition is by Rose (2nd ed., Leipzig, 1899); see also Nohl, Index Vitruvianus (1876) ; Jolles, Vitruvs 4esthetik (1906) ; Sontheimer, Vitruv and seine Zeit 1908) . There is a good translation by Gwilt (1826; reprinted, 1874) . The name of Vitruvius has been given to several works on modern architecture, such as Campbell, Vitruvius Britannicus (London, 1715-71), a series of illustrations of the chief buildings of the 18th century in England, including many works of the brothers Adam; one of these brothers, William Adam, produced a similar work illustrating the buildings which he had designed for Scotland, under the title of Vitruvius Scoticus (Edinburgh, 1790) . Thurah, Le Vitruve danois (Copenhagen, 1746-49), is a similar collection of modern buildings in Denmark . VITRY-LE-FRANcOIS, a town of north-eastern France, capital of the department of Marne, on the right bank of the Marne, 20 M . S.E. of Chalons, on the railway from Paris to Strassburg .

Pop . (1906) 7985 . The Marne-

Rhine canal, the Haute-Marne canal, and the lateral canal of the Marne unite at Vitry . Its church of Notre-Dame is a 17th-century building with fine" 18th-century monuments . A convent of the Recollets now contains' the town hall, the court-house, a library and a small museum . There is a bronze statue of P . P . Royer-Collard (1763-1845), the politician and philosopher, a native of the district . The industrial establishments include important cement works and the manufacture of faience is carried on . The present town was built in 1545 on a uniform plan by Francis I. to replace the older one of Vitry-en-Perthois, 2a m. to the north-east, burned in the previous year by Charles V .
