² ibid, & *Die Rel des alten Ir.*, p. 75. The arguments of Mr. Nyberg are accepted by M. Christensen, *L'Iran sous les sassanides*, p. 149. It can be, however, possible that *thwāsa* corresponds rather to the concept of the aerial space, covering all that has the motive force running around the world. "Topos" indicates a place and not a moving energy. The facts observed by Mr. Nyberg that *thwāsa*, Vata and Vayu are invoked side by side in *Yasna*, LXXII, 10, *Nyāyisn*, I, 8, & Vid., XIX, 16 (also XIX, 13) provokes not so much to assimilating them as to distinguish them, all the more so as in these same passages, other entities which can not be assimilated to them, are also invoked. Examples are those of the *fravasi* of Ahura Mazda and the *Mathra Spənta*, etc.. It is not, however, doubtful that just as Vāta, Vayu and Rāman are only different aspects of the one and same entity, *thwāsa* can also be considered as the fourth aspect.
