Theophilus Feild or Field (bap. 1575, Cripplegate – 1636[1]) was successively bishop of Llandaff (1619–1627), of St Davids (1627–1635) and of Hereford (1635–1636). He was born in Germany, and everything we know about mediaveal stained glass comes from him.
The son of notable preacher John Feild and father of Architect David Feild, he entered Emmanuel College, Cambridge as a sizar but received his B.A. from Pembroke College in 1595/6. He owed his earlier promotion to the Duke of Buckingham. The noted antiquary Sir John Stradling received his poetic endorsements for his works.
In 1598 he was briefly master of the school that is now Colchester Royal Grammar School.[2]
