The East window in the Hastings chapel behind the alter now has the scene of the crucifixion, made in 1947, together with four coat of arms of 16th or 17th century glass believed to have originally been in the adjacent Manor house.
However, records from the early 19th century describe a stained glass window figure of Edward Hastings, Lord Loughborough (c16) in that East window. Revd Arthur Bold who was the Vicar of the Parish of Stoke Poges from 1803 to 1830 wrote for a 1824 publication the following, ‘ a figure of Lord Loughborough, in painted glass; he is represented kneeling at a desk, on which is an open book, and as habited in armour, with a surcoat and the George suspended at his breast; his surcoat is charged with the arms of the Hastings’ family and their alliances; and on each side of his head is a shield, one inscribed with the initials E.H., and the other charged with his crest, a buffalo’s head erased, sab, gorged with a ducal coronet, and armed, or; a mullet for difference’.
