A papyrus discovered in Egypt in 1917 and dated to c. AD 250 contains the prayer Sub Tuum Praesidium — addressing Mary as Theotokos and asking for her intercession. This is liturgical Marian devotion two centuries before the Council of Ephesus.
The Sub Tuum Praesidium papyrus (P. Rylands 470) was discovered in 1917 and is now in the John Rylands Library in Manchester. Palaeographic analysis dates it to the late third century. The prayer is the earliest known text addressing Mary as Theotokos and asking for her intercession.

The argument that Marian devotion was a medieval Catholic innovation is simply incompatible with a papyrus datable to c. AD 250 containing a Marian prayer in liturgical use. The prayer was written down then, which means it existed already. The church in Egypt was praying to Mary as Theotokos before Nicaea.
