Many of the prayers and hymns in the Gospels have received text treatments throughout The Saint John’s Bible. This text illumination of the Lord’s Prayer is integrated within the text of the Gospel of Matthew, introduced with the words “pray then in this way” (Sink, 2013, p.215).
The use of heavy ruled lines under the text is synonymous with the manner in which ancient manuscripts were written, and were a means of keeping the calligrapher’s writing straight (Sink, 2013).
