Part of the Psalmodia service. According to Abu al-Barakat ibn Kabar, in his encyclopedia The Lamp of Darkness for the Explanation of the Service, the compiler of the Theotokia was a virtuous potter who became a monk in Scetis. He adds that some people consider St. Athanasius to be the author of the Theotokia. Some modern scholars such as G. Giamberardini and J. Muyser identified several resemblances between the homilies of Cyril of Alexandria during the Council of Ephesus and the Coptic Theotokia. The Theotokia in fact contains not only extracts from the Cyrillian homilies but also from those of Proclus of Cizicus, Theodotus of Ancyra, and especially Homily 67 of Severus of Antioch. The Theotokia could be dated between the sixth and the eighth centuries.
The Antiphonarion of the Monastery of Hamuli preserved in the Pierpont Morgan Library contains extracts from the Theotokia for the consecration of the church at Qalamon. This Sahidic manuscript is dated 892-893 a.d. The fragments from the Monastery of St. Macarius, preserved in the collection of the State Library of Hamburg, contain the Theotokia, and can be dated to the 12th or 13th century. For editions, see the entry on Psalmodia.
