Gustav Davidson (1994) says that “According to legend, Agares was one of the 72 spirits Solomon is reputed to have shut up in a brass vessel and cast into a deep lake (or banished to “lower Egypt”).”
Agares in the Pseudomonarchia Daemonum
Weir (1583) describes Agares as a First Duke of the East who appears as a fair old man riding a crocodile and carrying a hawk on his fist. He teaches languages, fetches back those who run away, and makes those who run stand still. He overthrows supernatural and temperal dignities and can cause earthquakes. He is of the order of Virtues and oversees thirty-one legions.

Agares in the Dictionaire Infernal
According to Collin de Plancy (1863), Aguares is a Grand Duke in the Eastern part of Hell. He is of the order of the virtues and governs thirty-one legions. He appears in the guise of a Lord riding a crocodile and carrying a goswhawk. He is said to make deserters return and can defeat enemies. He can give people dignities, teach all languages, and cause earthquakes.
Agares in the Goetia
S. L. MacGregor Mathers’ description of Agares is virtually identical to Weir’s description, other than including his seal.
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.
