[27] It appears in one of M. Massignon’s photographs; _Mission en Mésopotamie_, Plate XX [28] Dr. Reuther observed that in No. 69 the vault at the north end had been constructed without centering, while the vault at the south end had been constructed over a centering; _Ocheïdir_, p. 43. [29] Rooms 63 and 65 are vaulted without centering; _Ocheïdir_, p. 5. [30] As has been mentioned on p. 10, the original intention was to carry this same wall round the fourth side (the north side) also; but when the great outer wall was added to the scheme, it replaced the smaller, less important wall of the first design. [31] The authors of _Ocheïdir_ restore a south wall running from No. 150 to No. 152, thus converting the open space to the south of 141 into a court on the analogy of court F. I saw no trace of such a wall. [32] Dr. Reuther gives a detailed photograph (_Ocheïdir_, Fig. 50), showing a band of rhomboids round the window frame. [33] It was visited by Massignon and appears in his map, _Mission en Mésopotamie_, vol. i, p. 21. [34] Cf. the crenellated motive round the archivolt of the doors of corridors 5 and 6 at Ukhaiḍir. [35] M. Massignon heard of it under the name of Makhḍah or Madjḍah, but he did not visit it. Op. cit., p. 30. [36] Le Strange, _Lands of the Eastern Kaliphate_, p. 92.

He places it too far east in his map. [42] Cf. the east, west, and south gates of Ukhaiḍir. [43] Cf. a calotte in the central court at Ukhaiḍir, Plate 26, Fig. 2. [44] This seems to be the road to which al-Ḥadjdjâdj alludes (_Ṭabari_, vol. ii, p. 945): ‘And if you have come opposite to Hît, leave the Euphrates road and al-Anbâr and take your way to ‘Ain al-Tamr so that you may reach al-Kûfah.’ [45] _Mission scientifique en Perse_, vol. iv, Plates 40, 42, and 46. [46] Cf. with these passages the vaulted passages to one side of the lîwân groups at Ukhaiḍir in courts B, C, G, and H. [47] In the photograph there seems to be a low archway on the south side of the gate; it is, however, merely a hole in the wall, and I satisfied myself that there was originally no opening here.
