The third order was the Ovydd, or Ovate, to which the candidate could be immediately admitted without being obliged to pass through the regular disciplines. The requisite qualifications were, in general, an acquaintance with discoveries in science, the use of letters, medicine, language, and the like. On particular occasions, in consideration of other gifts, even the knowledge of, and a genius for, poetry might be dispensed with. The Ovydd was, however, enjoined to acquaint himself with the Bardic Institutes and traditions. For it might occur that the order of Ovates should alone continue, which in its original purity could not be done, unless they were acquainted with its true principles, nature and intention. The Ovydd could perform all the functions of Bardism; and by some particular performance he became entitled to other degrees, on the confirmation of a Gorsedd.

it is incumbent upon an Ovate to endeavour and seek after learning, as far as he can, by means of the hearing and voice of the world, of sight and contingency, and of attempt, awen, and imagination
