The science of heraldry has faithfully preserved to modern times various phases of some of those remarkable legends, which, based upon an accurate study of natural phenomena, exhibit the process whereby the greater part of mythology has come into existence. There we find the lunar Unicorn, the wild, white, fierce, chaste moon, whose two horns, unlike those of mortal creatures, are indissolubly twisted into one, a most remarkable myth, which I have recently fully considered; and there, also, as in every department of ancient thought, the solar power is fully represented. I now propose to examine, briefly, the ancient and widely-spread heraldic myth of the Gryphon.
