In 1749, when the west pediment was drawn by Dalton, many figures still remained in position which had disappeared before the time of Lord Elgin. Several portions also of the frieze, which were seen by Stuart, had disappeared at the beginning of the present century. On the other hand, the east pediment, being inaccessible, suffered no important change between 1674 and 1800. In the years 1801-3 many of the sculptures of the Parthenon were removed to England by the Earl of Elgin, then British ambassador at Constantinople, by means of a firman obtained from the Porte (see p. 6). The Elgin Collection, which includes other marbles obtained from Athens and elsewhere, together with casts and drawings, was purchased from Lord Elgin by the British Government in 1816 for £35,000. Several portions of the sculptures of the Parthenon have been discovered since the time of Lord Elgin on the Acropolis and its slopes, or in various parts of Europe, to which they had been taken by travellers. These are represented as far as possible in the British Museum by plaster casts. The following aids to the study of the Parthenon will be found in the Elgin Room:-- Model of the Athenian Acropolis, showing its condition in the year 1870. Presented by Prof. Adolf Michaelis. Model of the Parthenon. The model was made by R. C. Lucas, on a scale of a foot to 20 feet, and represents the state of the temple in 1687, after the explosion, but before Morosini had attacked the west pediment. Carrey's drawings of the pediments. Photographic reproductions of the originals are exhibited. A restored view of the Athenian Acropolis. By Richard Bohn. _Bibliography of the Parthenon._
