 It corresponds closely with the typical edition of 1498 of the Sarum Missal .Apart from its unique significance in Scottish religion, the Missal is a rare and important example of Scottish medieval art and letters – a large, beautifully preserved volume of 248 pages, lavishly decorated with twenty three-quarter page border illuminations and illustrations, as well as finely painted miniature initials spaced throughout the text.A striking full-page miniature painting of St Ternan, patron saint of the church of Arbuthnott, is modelled on William Scheves, Archbishop of St Andrews, and can claim to be one of the earliest Scottish portraits.
