Berlin, 1904, pp. 324 ff., 371 ff.--From a communication made to the
Congress of Orientalists at Copenhagen (1908) by Father Lammens, it would
appear that the façade of Mschatta is the work of an Omaiyad kalif of
Damascus, and Strzygowski's conclusions would, therefore, have to be
modified considerably; but the influence of Sassanid art in Syria is
nevertheless certain; see Dussaud, _Les Arabes en Syrie avant l'Islam_,
1907, pp. 33, 51 ff.
