The Key of Solomon is the most widely copied ritual-magic handbook of early modern Europe and the model against which most later grimoires defined themselves. Despite its claim to be a testament of King Solomon to his son Rehoboam, it is a Christian-era compilation. Its closest relative is the Greek Magical Treatise of Solomon (Hygromanteia), known from fifteenth-century manuscripts, and most scholars place the formation of the Latin and Italian Clavicula in late medieval or Renaissance Italy. There is no single authoritative text: hundreds of manuscripts survive in Latin, Italian, French, English, German, Dutch and Hebrew, and they differ widely in arrangement and content. The typical version falls into two books. The first covers prayers, confessions, conjurations of spirits, and the making of planetary pentacles, together with operations for invisibility, love, finding stolen goods and similar ends. The second covers the operator's purification and fasting, garments, consecrated knives and wands, the magic circle, ink, parchment, incense, and the planetary hours. The work was repeatedly banned and appears frequently in Inquisition records, especially in Venice, which shows how widely it circulated among clergy, physicians and cunning folk. S. L. MacGregor Mathers' English edition of 1889, compiled from several British Library manuscripts, made it a foundational text of the Golden Dawn and of modern ceremonial magic. Today the Key is studied as a tradition of related texts rather than a single book, and editors increasingly publish individual manuscript families instead of composite texts.

Recent scholarship

Federico Barbierato's study of magic books before the Venetian Inquisition appeared in English in 2025, and in 2026 Gal Sofer published a sixteenth-century Hebrew Clavicula leaf that challenges the view that Hebrew versions only arose in the late seventeenth century. Joseph Peterson continues to publish individual manuscripts (VSG 334, Aubrey 24) as free transcriptions.
