Clement of Alexandria clearly knew of Marcus and actually used his system of mystical numbers (four, six, eight, ten, twelve, thirty), though without acknowledgement.
His system tells of 30 aeons, divided into an Ogdoad, a Decad, and a Dodecad; of the fall and recovery of Sophia; of the future union of the spirits of the chosen seed with angels as their heavenly bridegrooms.
What Marcus added to the teaching of his predecessors was a system of Isopsephy similar to that of the later Pythagoreans, about mysteries in numbers and names.
Marcus found in Scripture and in Nature repeated examples of the occurrence of his mystical numbers, four, six, eight, ten, twelve, thirty.
Irenaeus alleges that Marcus abused his influence over "silly women" in order to gain both money and sexual favors.
