E´MPULUM(Ampiglione), a small town of Latium, a dependency of Tibur, which was taken in B.C.355 by the Roman consuls. (Liv. 7.18.) This is the only mention of its name, and we have no clue to its position; but the resemblance of name has induced Gell and Nibby to regard the remains of an ancient town visible at a place called Ampiglione(about 5 miles E. of Tivoli, on the road to Siciliano), as those of Empulum. Considerable portions of the walls remain, constructed of polygonal blocks of tufo—the only instance of the employment of that material in this style of construction; but they are not of a massive character, and are intermixed with portions of reticulated and other masonry, decidedly of the Roman period. The site was probably used in later times as that of a Roman villa. (Gell, Top. of Rome, pp. 199-201; Nibby, Dintorni, vol. ii. pp. 10, 11.)
