"Stained-glass panel, 1660-1700. By 1824, there were 150 parishes within the metropolitan area, each with a parish clerk. London's local government depended upon these clerks. Those in the City of London drew up the bills of mortality of their parishes. The two stained-glass panels of St Cecilia and King David represent the parish clerks' responsibility for church music. Lent by the Worshipful Company of Parish Clerks."
