Diagram Of The Shield Of The Trinity, In A Compilation Of John Of Wallingford's Works
Medium: Ink and pigments on vellum
Parts of the manuscript were written and illustrated while he was at St. Albans, but other parts date to the final year of his life, when he was at Wymondham, a few miles south-west of Norwich. This drawing shows a shield, marked in the roundels with the names of the Trinity: 'Father', 'Holy Spirit' and 'God' (the lowermost one is damaged, but would have read 'Son'). Two demons are shooting arrows at the superimposed image of the Crucifixion, but the arrows are falling to the ground at their feet, broken.
