The Testament of Solomon was originally written in Greek, and scholars date it to the end of the first century, but it includes material dated to an earlier period. The text contains various theological and magical themes found in Christianity and Judaism, and Greek and Egyptian mythology. It contains passages on medical alchemy and incorporates astrological concepts. Most of it consists of Solomon's interviews with demons, including figures otherwise known as the Titan Kronos, Lilith, Hecate, and Medusa.
