The above information explains the origin of the legend. Two fixed points were in existence: the pious poet of _c._ 460 and the atheist who was outlawed in 415; a bridge was constructed between them by the story of the stolen ode. This disposes of the whole supposition of atheism growing out of a basis of experience. But, furthermore, it must be admitted that it is doubtful whether the poet and the atheist are one and the same person. The interval of time between them is itself suspicious, for the poet, according to the ancient system of calculation, must have been about forty years old in 464, consequently between eighty and ninety in 415. (There is general agreement that the treatise, the title of which has been quoted, must have been a later forgery.) If, in spite of all, I dare not absolutely deny the identity of the two Diagorases of tradition, the reason is that Aristophanes, where he mentions the decree concerning Diagoras, seems to suggest that his attack on the Mysteries was an old story which was raked up again in 415. But for our purpose, at any rate, nothing remains of the copious mass of legend but the fact that one Diagoras of Melos in 415 was outlawed in Athens on the ground of his attack on the Mysteries. Such an attack may have been the outcome of atheism; there was no lack of impiety in Athens at the end of the fifth century. But whether this was the case or not we cannot possibly tell; and to throw light on free-thinking tendencies in Athens at this time, we have other and richer sources than the historical notice of Diagoras.
