The ‘Magical Treatise of Solomon’ and the ‘Key of Solomon’ are two grimoires (magic handbooks) commonly said to have been written by the biblical King Solomon. The latter grimoire has been described as “The most enduring, influential, and notorious Solomonic book,” and much has been written on it.
English translations of ‘Key of Solomon’ can be found easily. By contrast, the ‘Magical Treatise of Solomon’ is not as well-known and much less has been written about it. Nevertheless, this grimoire is regarded as the precursor to the ‘Key of Solomon.’

This text is the ancestor of the famous ‘Key of Solomon.’
