The notion of Tintagel being a “mystery center” associated with a pre-Christian cult is a concept proposed by the Austrian philosopher and esotericist Rudolf Steiner. Steiner, the founder of Anthroposophy, a spiritual movement that seeks to integrate spirituality with science and art, suggested that Tintagel served as a focal point for mystical and spiritual activities in prehistoric and early medieval times.
According to Steiner’s interpretation, Tintagel was believed to have been the center of a mystery cult, akin to other ancient mystery schools or esoteric traditions found throughout the ancient world. These mystery cults were often associated with secret rituals, initiation ceremonies, and the worship of deities or spiritual principles.
In Steiner’s view, individuals who held the title of “Arthur” were the leaders or high prieces of this mystery cult at Tintagel. The name “Arthur” may have been used symbolically to represent the role of these leaders rather than referring to specific historical figures. Steiner suggested that these Arthurs played a significant role in guiding the spiritual development and practices of the community associated with Tintagel.
It’s important to note that Steiner’s ideas about Tintagel as a mystery center and the role of Arthurs in ancient Britain are speculative and not supported by mainstream historical or archaeological evidence. However, his interpretations reflect his broader interest in mythology, spirituality, and the esoteric dimensions of history.
