Agares, also known as Agarat, Agaros or Agarus, is the second demonic spirit of the Ars Goetia, summoned by King Solomon. He is the first duke of the eastern realm of Hell who appears as a fair old man or handsome 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. Agares commands 31 to 33 legions of demons and has the power to cause earthquakes and cause runaways to stop and return to their place.
He was of the order of virtues and holds the ability to overthrow supernatural and temporal dignities. The Book of the Office of Spirits places him under Oriens and describes him as an old man riding a cockatrice, sans hawk. Agares is reputed to have been sealed in a brass vessel and cast into a deep lake or banished to "lower Egypt" and also appears in the form of a lord riding a crocodile and carrying a Peregrine falcon. He is said to make deserters return and can defeat enemies and finding pleasure in teaching immoral expressions
According to the Grand Grimoire, he is a direct subordinate of Lucifuge Rofocale. According to Thomas Rudd, Agares is opposed by the Shemhamphorasch angel Jelial.
"One of the 72 demons of the Goetia. He is a Grand Duke that rules the eastern zone of Hell. He rides various grotesque creatures, like crocodiles, and appears as an old sage with a hawk on his arm. He grants words of wisdom to those who summon him and will bring back fugitives who escaped the summoner. He also causes destruction through earthquakes."
