The demon Seere appears in the grimoires Book of Incantations and The Lesser Key of Solomon
From The Lesser Key of Solomon, Crowley/Mathers edition:
The Seventieth Spirit is Seere, Sea, or Seir. He is a Mighty Prince, and Powerful, under AMAYMON, King of the East. He appeareth in the Form of a Beautiful Man, riding upon a Winged Horse. His Office is to go and come; and to bring abundance of things to pass on a sudden, and to carry or re-carry anything whither thou wouldest have it to go, or whence thou wouldest have it from. He can pass over the whole Earth in the twinkling of an Eye. He giveth a True relation of all sorts of Theft, and of Treasure hid, and of many other things. He is of an indifferent Good Nature, and is willing to do anything which the Exorcist desireth.
