Alcibiades (34.4-34.5)

Accordingly, it seemed to Alcibiades that it would be a fine thing, enhancing his holiness in the eyes of the gods and his good repute in the minds of men, to restore its traditional fashion to the sacred festival by escorting the rite with his infantry along past the enemy by land. He would thus either thwart and humble Agis, if the king kept entirely quiet, or would fight a fight that was sacred and approved by the gods, in behalf of the greatest and holiest interests, in full sight of his native city, and with all his fellow citizens eye-witnesses of his valor.

When he had determined upon this course and made known his design to the Eumolpidae and Heralds, he stationed sentries on the heights, sent out an advance-guard at break of day, and then took the priests, mystae, and mystagogues, encompassed them with his men-at-arms, and led them over the road to Eleusis in decorous and silent array. So august and devout was the spectacle which, as general he thus displayed, that he was hailed by those who were not unfriendly to him as High Priest, rather, and Mystagogue.
