The magi, the Sephoe, the gymnosophists, and the Irish adepts, held much the same creed and the same dogmas with regard to the conduct of life necessary to heighten the spiritual power. They all abstained from animal food at such times as the rush of inspiration was on them and the madness of prophetic rage ; and at all times they favoured solitude, living apart in the House of Learning or Bardic College, where they admitted no obtrusive intimacies with lower intellects to disturb their lofty and exalted moods of thought. The means, also, by which they obtained mastery over diseases and the minds of men, with the strange and subtle use they made of herbs, were all kept secret amongst themselves ; for they held that the prying eyes of shallow unbelievers should never be suffered to intrude upon the sacred mysteries. And it is certain that the bards possessed strange and mystic powers of wisdom beyond and above all other men. It was therefore very dangerous to offend a poet. If any one refused him a request he would take the lobe of the person's ear and grind it between his fingers, and the man would die. Yet the bards were capable of much human emotion, and were the sweet singers of sympathy when sorrow touched a household.
