Marconites

To take craziness to frontiers it has never reached before, seems to have been the motto of the followers of Marcus. Irenaeus describes him as a gnostic magician, who used his tricks to seduce and take advantage of rich women, single or married. Marcus' follows the Valentinus system, adding in a greater concern with numerology, especially Gematria.

In his rebuke of Marcus, it is important to note that Irenaeus does not refute his prophecy by claiming that the gift of prophecy had ceased, rather he refers to it as a fraud or demon-inspired.
