And thus Hermes becomes the spirit of the movement of the sky or
firmament; not merely the fast flying of the transitory cloud, but the
great motion of the heavens and stars themselves. Thus, in his highest
power, he corresponds to the "primo mobile" of the later Italian
philosophy, and, in his simplest, is the guide of all mysterious and
cloudy movement, and of all successful subtleties. Perhaps the prettiest
minor recognition of his character is when, on the night foray of Ulysses
and Diomed, Ulysses wear the helmet stolen by Autolycus, the son of
Hermes.

29. The position in the Greek mind of Hermes as the lord of cloud is,
however, more mystic and ideal than that of any other deity, just on
account of the constant and real presence of the cloud itself under
different forms, giving rise to all kinds of minor fables. The play of
the Greek imagination in this direction is so wide and complex, that I
cannot give you an outline of its range in my present limits. There is
first a great series of storm-legends connected with the family of the
historic Æolus centralized by the story of Athamas, with his two wives,
"the Cloud," and the "White Goddess," ending in that of Phrixus and
Helle, and of the golden fleece (which is only the cloud-burden of Hermes
Eriophoros). With this, there is the fate of Salmoneus, and the
destruction of the Glaucus by his own horses; all these minor myths of
storm concentrating themselves darkly into the legend of Bellerophon and
the Chimæra, in which there is an under story about the vain subduing of
passion and treachery, and the end of life in fading melancholy,--which,
I hope, not many of you could understand even were I to show it you (the
merely physical meaning of the Chimæra is the cloud of volcanic lightning
connected wholly with earth-fire, but resembling the heavenly cloud in
its height and its thunder). Finally, in the Æolic group, there is the
