Agares

Agares: According to Wierius (q.v.) Grand Duke of the eastern region of Hades.  He is shown under the form of a benevolent lord mounted on a crocodile, and carrying a hawk on his first.  The army he protects in battle is indeed fortunate, for he disperses their enemies, and puts new courage into the hearts of the cowards who fly before superior numbers.  He distributes place and power, titles and prelacies, teaches all languages, and has other equally remarkable powers.  Thirty-one legions are under his command. (b)

Aguares, a grand duke of the eastern regions of Hell, had 30 legions under his command.  A master linguist, he was also known to incite dancing among mortals.  (c)

AGARES. - The Second Spirit is a Duke called Agreas, or Agares. He is under the Power of the East, and cometh up in the form of an old fair Man, riding upon a Crocodile, carrying a Goshawk upon his fist, and yet mild in appearance. He maketh them to run that stand still, and bringeth back runaways. He teaches all Languages or Tongues presently. He hath power also to destroy Dignities both Spiritual and Temporal, and causeth Earthquakes. He was of the Order of Virtues. He hath under his government 31 Legions of Spirits. And this is his Seal or Character which thou shalt wear as a Lamen before thee. (h)
