Note 506 — CANTO THE FOURTH[375]

[Compare The Deformed Transformed, act i. sc. 2, lines 49, 50—

The first, second, and third stories of the Flavian amphitheatre or Colosseum were built upon arches. Between the arches, eighty to each story or tier, stood three-quarter columns. "Each tier is of a different order of architecture, the lowest being a plain Roman Doric, or perhaps, rather, Tuscan, the next Ionic, and the third Corinthian." The fourth story, which was built by the Emperor Gordianus III., A.D. 244, to take the place of the original wooden gallery (manianum summum in ligneis), which was destroyed by lightning, A.D. 217, was a solid wall faced with Corinthian pilasters, and pierced by forty square windows or openings. It has been conjectured that the alternate spaces between the pilasters were decorated with ornamental metal shields. The openings of the outer arches of the second and third stories were probably decorated with statues. The reverse of an aureus of the reign of Titus represents the Colosseum with these statues and a quadriga in the centre. About one-third of the original structure remains in situ. The prime agent of destruction was probably the earthquake ("Petrarch's earthquake") of September, 1349, when the whole of the western side fell towards the Cælian, and gave rise to a hill or rather to a chain of hills of loose blocks of travertine and tufa, which supplied Rome with building materials for subsequent centuries. As an instance of wholesale spoliation or appropriation, Professor Lanciani refers to "a document published by Müntz, in the Revue Arch., September, 1876," which "certifies that one contractor alone, in the space of only nine months, in 1452, could carry off 2522 cartloads" of travertine (Smith's Dict. of Gr. and Rom. Ant., art. "Amphitheatrum;" Ruins and Excavations of Ancient Rome, by R. Lanciani, 1897, p. 375).]
