The Key of Solomon is a grimoire or book on magic attributed to King Solomon (as several others were). The known copies originated in the Middle Ages and later. The book contains several paragraphs and terms inspired by Talmudic texts and the Jewish Kabbalah teaching.
It is possible that the Key of Solomon inspired later works such as the Lemegeton, also called The Lesser Key of Solomon, although there are many differences between both books. What may have inspired the Lemegeton are the conjurations and rituals of purification, and in a less important way, the clothing and magic symbols.
Several versions of the Key of Solomon exist, in various translations, and with minor or significant differences. Most manuscripts date to the 16th or 17th century, but a prototype in Greek still survives from the 15th century.
