This is the very same diction that Philo uses about the Therapeut communities, which he declares were very numerous in every province of Egypt and scattered in all lands. We are not, however, to suppose that these communities were all of the same nature. It is true that Philo tries to make out that the most pious and the chief of all of them was his particular community on the southern shore of Lake Mœris, which was strongly Semitic if not orthodoxly Jewish; and for Philo any community with a Jewish atmosphere must naturally have been the best. The peculiarity and main interest of our community, which was at the other end of the land above the cataracts, was that it had had some remote connection with India.

The community is called a φροντιστήριον, in the sense of a place for meditation, a term used by ecclesiastical writers for a monastery, but best known to classical students from the humorous use made of it by Aristophanes, who in The Clouds calls the school of Socrates, a phrontistērion or “thinking shop.” The collection of monasteria (ἱερά), presumably caves, shrines, or cells,[107] was situated on a hill or rising ground not far from the Nile. They were all separated from one another, dotted about the hill, and ingeniously arranged. There was hardly a tree in the place, with the exception of a single group of palms, under whose shade they held their general meetings (vi. 6).

It is difficult to gather from the set speeches, put into the mouths of the head of the community and Apollonius (vi. 10-13, 18-22), any precise details as to the mode of life of these ascetics, beyond the general indications of an existence of great toil and physical hardship, which they considered the only means of gaining wisdom. What the nature of their cult was, if they had one, we are not told, except that at mid-day the Naked retired to their monasteria (vi. 14).

The whole tendency of Apollonius’ arguments, however, is to remind the community of its Eastern origin and its former connection with India, which it seems to have forgotten. The communities of this particular kind in southern Egypt and northern Ethiopia dated back presumably some centuries, and some of them may have been remotely Buddhist, for one of the younger members of our community who left it to follow Apollonius, says that he came to join it from the enthusiastic account of the wisdom of the Indians brought back by his father, who had been captain of a vessel trading to the East. It was his father who told him that these “Ethiopians” were from India, and so he had joined them instead of making the long and perilous journey to the Indus itself (vi. 16).

If there be any truth in this story it follows that the founders of this way of life had been Indian ascetics, and if so they must have belonged to the only propagandising form of Indian religion, namely, the Buddhist.

After the impulse had been given, the communities, which were presumably recruited from generations of Egyptians, Arabs, and Ethiopians, were probably left entirely to themselves, and so in course of time forgot their origin, and even perhaps their original rule. Such speculations are permissible, owing to the repeated assertion of the original connection between these Gymnosophists and India. The whole burden of the story is that they were Indians who had forgotten their origin and fallen away from the wisdom.

The last incident that Philostratus records with regard to Apollonius among the shrines and temples is a visit to the famous and very ancient oracle of Trophonius, near Lebadea, in Bœotia. Apollonius is said to have spent seven days alone in this mysterious “cave,” and to have returned with a book full of questions and answers on the subject of “philosophy” (viii. 19). This book was still, in the time of Philostratus, in the palace of Hadrian at Antium, together with a number of letters of Apollonius, and many people used to visit Antium for the special purpose of seeing it (viii. 19, 20).

In the hay-bundle of legendary rigmarole solemnly set down by Philostratus concerning the cave of Trophonius, a small needle of truth may perhaps be discovered. The “cave” seems to have been a very ancient temple or shrine, cut in the heart of a hill, to which a number of underground passages of considerable length led. It had probably been in ancient times one of the most holy centres of the archaic cult of Hellas, perhaps even a relic of that Greece of thousands of years b.c., the only tradition of which, as Plato tells us, was obtained by Solon from the priests of Saïs. Or it may have been a subterranean shrine of the same nature as the famous Dictæan cave in Crete which only last year was brought back to light by the indefatigable labours of Messrs. Evans and Hogarth.

As in the case of the travels of Apollonius, so with regard to the temples and communities which he visited, Philostratus is a most disappointing cicerone. But perhaps he is not to be blamed on this account, for the most important and most interesting part of Apollonius’ work was of so intimate a nature, prosecuted as it was among associations of such jealously-guarded secrecy, that no one outside their ranks could know anything of it, and those who shared in their initiation would say nothing.

It is, therefore, only when Apollonius comes forward to do some public act that we can get any precise historical trace of him; in every other case he passes into the sanctuary of a temple or enters the privacy of a community and is lost to view.
