The Hymns of Hermes - G. R. S Mead - Bog

Thoth, as the inspirer of all sacred writings and the president of all priestly discipline, was, as Iamblichus tells us, a name which was held by the Egyptians to be "common to all priests"-that is to say, every priest as priest was a Thoth, because he showed forth in his sacred office some characteristic or other of the Great Priest or Master Hierophant among the Gods whose earthy name was Thoth Tehuti.
Thoth was thus the Oversoul of all priests; and when some of the Greeks came to know better what the inner discipline of the true priestly mysteries connoted, they so felt the inadequacy of plain Hermes as a suitable equivalent for the Egyptian name which designated this great ideal, that they qualified 'Egyptian Hermes' with the honorific epithet 'Thrice-greatest.'
It is of the Hymns of this Thrice-greatest Hermes that I shall treat in the present small volume hymns that were inspired by the still-living tradition of what was best in the wisdom of ancient Egypt, as 'philosophized' through minds trained in Greek thought, and set forth in the fair speech of golden-tongued Hellas.
