XVIII. _Persian Room._—The sculptures to be here exhibited, which are all bas-reliefs, would probably not occupy more than half the wall-space, which is forty-seven linear feet. They belong chiefly to the sixth century, B.C., and properly therefore succeed the Assyrian, which range from the tenth to the seventh century, B.C. [Sidenote: LYCIAN GALLERY.] XIX. _Lycian Gallery._—It is intended to reserve this room for the monuments peculiarly characteristic of Lycia, and to transfer to the Greek galleries those in which the Greek element is predominant; such as, particularly, the sculptures of the Ionic trophy monument or _heroum_ from Xanthus, now scattered over the room, and, if necessary, the casts from the rock tomb at Myra. This would leave abundant space for the purely Lycian remains. The harpy tomb, of which the bas-reliefs furnish a very important illustration of archaic Greek art, might best be placed in an isolated position near the entrance to the Greek galleries, where it would be favourably lighted and conspicuously seen. Its present place might be filled by the rude sarcophagus with sculptures of lions. The lighting of the Lycian room, which is very defective, should be improved by an alteration in the roof; but it is thought better not to enter into the details of such alteration in the present paper. [Sidenote: FIRST GREEK ROOM.] XX. _First Greek or Inscription Room._—The room beneath this being supposed to be withdrawn from exhibition, the staircase at the west end should be separated by a partition, and entered through a private door. All Greek inscriptions, except the sepulchral, and such as are engraved on architectural or sculptural monuments, would be here collected. At this point the new buildings commence with— [Sidenote: SECOND GREEK ROOM.] XXI. _Second Greek or Branchidæ Room_, thirty feet by twenty-four.—The height both of this and the four succeeding rooms should be about twenty feet. This would contain the earliest Greek sculptures, of which the principal are those procured by Mr. NEWTON from Branchidæ. The ten seated statues would be arranged on each side, as in the ‘Sacred Way’ at that place, and the recumbent inscribed lion and the sphinx placed at the end of the room. [Sidenote: THIRD GREEK ROOM.] XXII. _Third Greek Room_, twenty-four feet by seventeen.—This would contain other archaic works, including the casts from Selinus. [Sidenote: FOURTH GREEK ROOM.] XXIII. _Fourth Greek or Æginetan Room_, thirty-eight feet by twenty-four.—Here would be fixed, in two recesses, the restorations of the two pedimental groups from Ægina, which are exactly of the length of this room, and which might be placed at a more convenient level for examination than their present elevated position in room.
