Thomas Jervais (or Gervais), who was born in Dublin, worked as a glass painter in Dublin before moving to London.
He is known for his “naturalistic” style of enamel glass painting, where he used glass as a canvas for detailed pictorial works rather than traditional leaded patterns. He is best known as the creator of the west window at New College, Oxford, based on a design by Joshua Reynolds. For Ireland he executed a window for the private chapel at Dangan; showing St Paul preaching at Athens after Raphael, this was moved to the Church of Ireland church at Agher, Co. Meath.
Other works in Ireland are noted by Strickland: ‘For the Duke of Leinster he executed some stained glass, which was formerly in the bow-window in the large room in Leinster House; and did several windows for Lord Charlemont at Marino, which were destroyed by fire in March, 1807. Three windows by him were formerly in Rathfarnham Castle, as recorded by Austin Cooper in 1781; but they have now disappeared.’
