says Empedocles. But about Cydnus, and the sacred sword of Apollo at Tarsus, we used to hear the story from you, dear Demetrius, how Cydnus cleans that steel best, and no other water suits the sword. And again, at Olympia, water from [Sidenote: C] Alpheus is poured on the ashes to make them adhere to the altar in a mass, and the water of no other river which has been found has the power of cementing the ash. XLII. ‘It is not to be wondered at, then, that of the many streams which the earth sends up, these alone affect souls with inspiration and give them imagination of the future. Certainly legend agrees with reason as to this.
