Goetia – S. L. MacGregor Mathers (1904) (quoted)
The Fifty-third Spirit is Camio, or Caim. He is a Great President, and appeareth in the Form of the Bird called a Thrush at first, but afterwards he putteth on the Shape of a Man carrying in his Hand a Sharp Sword. He seemeth to answer in Burning Ashes, or in Coals of Fire. He is a Good Disputer. His Office is to give unto Men the Understanding of all Birds, Lowing of Bullocks, Barking of Dogs, and other Creatures; and also of the Voice of the Waters. He giveth True Answers of Things to Come. He was of the Order of Angels, but now ruleth over 30 Legions of Spirits Infernal. His Seal is this, which wear thou, etc.
Pseudomonarchia daemonum – Johann Wier (1583) (quoted)
Caim is a great president, taking the forme of a thrush, but when he putteth on man’s shape, he answereth in burning ashes, carrieng in his hand a most sharpe swoord, he maketh the best disputers, he giveth men the understanding of all birds, of the lowing of bullocks, and barking of dogs, and also of the sound and noise of waters, he answereth best of things to come, he was of the order of angels, and ruleth thirtie legions of divels.
Dictionnaire Infernal – Collin de Plancy (1863) (paraphrased)
Once with the order of angels, and currently, high president of hell, Caym commands 30 legions. He appears in the form of a blackbird, a main coifed with a headdress & adorned with a peacock tail, or human carrying a tapering sword, & responds from the midst of a burning brazier. It is said that Caym is the most wise occupant of hell, and that he could outwit even the most seasoned logician. It was with him that Luther had his famous dispute from which he spared us the details. Caym teaches communication with animals and waves and knows of the future.
