Wadi El Natrun
This liturgical text derives from the West Syriac Rite, being imported in Egypt after the 6th-century from Syriac monks who settled in Wadi El Natrun. The authorship of the core of this anaphora by Gregory of Nazianzus himself cannot be excluded. The text however was adapted to the Egyptian use, and it was one of the three anaphoras which use was permitted by the canons of Patriarch Gabriel II in the 12th century.
