[87] Hilprecht, _Explorations in Bible Lands_, p. 564, compares it to the ancient Greek houses at Delos, for which see Durm, _Baukunst der Griechen_, p. 516. The juxtaposition of megaron and andron, each group of rooms opening into its own court, recalls irresistibly a yet older type; cf. the plan of Tiryns, Perrot-Chipiez, _Histoire de l’Art_, vol. vi, Plate 2. It is curious to note that the audience halls at Niffer are the oriental latitudinal chambers; indeed they have the closest connexion with the old Babylonian house type, which, as Professor Koldewey has observed, postulates invariably a court with a large chamber to the south of it. The Niffer palace is little more than a reproduction of such houses as the big house in the Merkes at Babylon, plus the column, which was due to Greek influence. See Koldewey, _Das wieder erstehende Babylon_, pp. 279 et seq. [88] _Mitt, der D. O.-G._, No. 25, p. 39. [89] Ibid., No. 28, p. 59.

The plan is given on Plate 4 of Andrae’s _Festungswerke von Assur_. [92] Andrae, _Hatra_, pt. ii, Plate 6. [93] The literature on this subject is of vast extent. See Choisy, _L’Art de bâtir chez les Byzantins_, p. 32; Dieulafoy, _L’Art antique de la Perse_, vol. iv, p. 14; Perrot-Chipiez, vol. ii, pp. 143-7, 163-81, 231-46.
