The Marcosians were a Gnostic sect founded by Marcus, active in Lyon, France and southern Europe from the second to the 4th century. Women held special status in the Marcosian communities; they were regarded as prophetesses and participated in administering the Eucharistic rites. Irenaeus accuses Marcus of seducing his followers, and scornfully writes (Adversus Haereses I. 13, 4) that the whole sect was an affair of "silly women."
