If we thus dismiss, as fruitless for our investigation, the most famous representative of the Hellenic Mysteries proper, how does the question stand with regard to those faiths to which Cumont is referring, the hellenized cults of Asia Minor?

Here the evidence, not merely of the existence of Mysteries, but of their widespread popularity, and permeating influence, is overwhelming; the difficulty is not so much to prove our case, as to select and co-ordinate the evidence germane to our enquiry.

Regarding the question as a whole it is undoubtedly true that, as Anrich remarks, “the extent of the literature devoted to the Mysteries stands in no relation whatever (gar keinem Verhältniss) to the importance in reality attached to them."[7] Later in the same connection, after quoting Clement of Alexandria’s dictum “Geheime Dinge wie die Gottheit, werden der Rede anvertraut, nicht der Schrift,” he adds, “Schriftliche Fixierung ist schon beinahe Entweihung."[8] A just remark which it would be well if certain critics who make a virtue of refusing to accept as evidence anything short of a direct and positive literary statement would bear in mind.  There are certain lines of research in which, as Bishop Butler long since emphasized, probability must be our guide.

Fortunately, however, so far as our present research is concerned, we have more than probability to rely upon; not only did these Nature Cults with which we are dealing express themselves in Mystery terms, but as regards these special Mysteries we possess clear and definite information, and we know, moreover, that in the Western world they were, of all the Mystery faiths, the most widely spread, and the most influential.

As Sir J. G. Frazer has before now pointed out, there are parallel and over-lapping forms of this cult, the name of the god, and certain details of the ritual, may differ in different countries, but whether he hails from Babylon, Phrygia, or Phoenicia, whether he be called Tammuz, Attis, or Adonis, the main lines of the story are fixed, and invariable.  Always he is young and beautiful, always the beloved of a great goddess; always he is the victim of a tragic and untimely death, a death which entails bitter loss and misfortune upon a mourning world, and which, for the salvation of that world, is followed by a resurrection.  Death and Resurrection, mourning and rejoicing, present themselves in sharp antithesis in each and all of the forms.

We know the god best as Adonis, for it was under that name that, though not originally Greek, he became known to the Greek world, was adopted by them with ardour, carried by them to Alexandria, where his feast assumed the character of a State solemnity; under that name his story has been enshrined in Art, and as Adonis he is loved and lamented to this day.  The Adonis ritual may be held to be the classic form of the cult.

But in Rome, the centre of Western civilization, it was otherwise:  there it was the Phrygian god who was in possession; the dominating position held by the cult of Attis and the Magna Mater, and the profound influence exercised by that cult over better known, but subsequently introduced, forms of worship, have not, so far, been sufficiently realized.
