In Greek mythology, Dolos (sometimes pronounced "Dolus") is the spirit of trickery and guile. He is also a master at cunning deception, craftiness, and treachery. He is apprentice of the Titan Prometheus, and Pseudologi. His female counterpart is Apate who is the goddess spirit of fraud and deception. He was parented by the Titans Gaia and Ather (Hyginus Preface) or Erebos and Nyx (Cicero, De Natura Deorum 3.17). He became a master at his skill when he attempted to make a statue of Veritas again, in order to trick people into thinking they were seeing the real statue. But he ran out of clay, which he was using to create the statue, and had to leave the feat unfinished as he quaked in fear while his skill-master overviewed his attempt at deceitfulness. But to his surprise, Prometheus was rather included and amazed at the similarity between the statues, then Dolos became the master at his crafty and tricky ways. There are even some stories of Dolos tricking gods into lies.

For example: In any church healing movement, those who experience 'temporary healing' are just 10% of attendance.
