Century Dictionary and Cyclopedia

1. n. A follower of Marcus, perhaps of Ephesus, a heresiarch of the second century. The leading features of his system were a ritual imitating the Christian eucharist (at which he apparently caused a miraculous change in the color and quantity of the wine), ministration and prophecy of women, a cabalistic use of numbers and letters, antinomian licentiousness, and a Gnostic system of eons. He is known chiefly from the writings of Irenæus, and his followers were not numerous.
