The Greater and Lesser Keys of Solomon the King

Solomon wrote The Greater Key for his son Rehoboam, and commanded him to hide the book in his sepulchre upon his death. After many years the book was discovered by a group of Babylonian philosophers repairing Solomon's tomb. None could interpret the text, until one of them, Iohé Grevis, suggested that they should ask the Lord for understanding. The Angel of the Lord appeared to him and extracted a promise that he would keep the text hidden from the unworthy and the wicked, after which he was able to read it plainly. Iohé Grevis then placed a spell on the book that the unworthy, the unwise or those who did not fear God would not attain the desired effect from any of the workings contained in the book.The Lesser Key of Solomon, also known as Salomonis Regis or Lemegeton, is an anonymous grimoire on demonology. It was compiled in the mid-17th century, mostly from materials a couple of centuries older.
