The Sorcery of Solomon by Sara L. Mastros

"The Key of Solomon is a family of closely related historic grimoires legendarily attributed to Solomon, the biblical Magician King. Most famously, Samuel Liddell MacGregor Mathers’s 1889 English edition presented forty-four Hebrew seals, commonly called the “planetary pentacles.” However, it offered very little guidance for how to work with them. Sara L. Mastros, a leading teacher and practitioner of magic, translates and interprets each of these pentacles and presents practical methods for working with their magical powers, creating a clear, accessible user’s guide."
