This language variety of Coptic was used in Northern Egypt, particularly in the area of the Delta. Unfortunately, there are very few texts preserved in Bohairic from the earliest times of Coptic literary production (4th to 6th century). They show peculiar features shared with other dialects like Mesokemic and Fayyumic (P. Mich. Inv. 5421). The bulk of the texts in Bohairic dates not earlier than the 10th century. Bohairic is the only Coptic dialect used in Egypt from the Middle Ages onwards, and it is still used today as the liturgical language of the Coptic church.
