Buer is a spirit described in several grimoires, most notably the *Ars Goetia* of *The Lesser Key of Solomon*, a well-known text in Western occult traditions. He is considered one of the 72 demons or spirits that King Solomon allegedly bound and controlled. Buer is classified as a Great President of Hell, commanding 50 legions of spirits.
He is associated with philosophy, logic, and healing. Buer is said to teach moral and natural philosophy, as well as the properties of herbs and plants. He also has the power to heal the sick and infirm.
In terms of appearance, Buer is traditionally depicted as having the shape of a lion’s head surrounded by five goat-like legs that radiate outward, allowing him to roll in all directions—a symbolic image representing his omnidirectional knowledge and movement.
In esoteric spirituality and energy work, Buer may be invoked for guidance in ethical decision-making, acquiring herbal knowledge, or promoting health and healing. When working with such energies, practitioners often engage in ritual, meditation, and protective measures to ensure safe and respectful contact.
