This document summarizes the story of Merlin as told by Robert de Boron. It describes how the demons, angry at being defeated by Jesus Christ, decided in a council to create an Antichrist through the impregnation of a woman by an incubus demon. Their goal was to mislead humanity away from the path of Christ. Merlin was born from this unholy union and was given powers of prophecy and knowledge to deceive people, but instead he used his gifts to serve God and prepare the way for King Arthur.
