These openings occur in the great Sassanide palace at Ctesiphon, the Takht-i-Khosrou (ibid. pl. 216, and text, p. 175). Here the terra-cotta pipes are about eight inches in diameter. According to these writers similar contrivances are still in use in Persia.
[227] In the cupola of the palace at Sarbistan (Fig. 54), a window may be perceived in the upper part of the vertical wall, between the pendentives of the dome. Such openings may well have been pierced under Assyrian domes. From many of the illustrations we have given, it will be seen that the Ninevite architects had no objection to windows, provided they could be placed in the upper part of the wall. It is of windows like ours, pierced at a foot or two above the ground, that no examples have been found.
