SIR JOHN AND LADY de HARDRESHULL, PANEL (c. 1400)
Artist unknown
Merevale Abbey in Warwickshire was built in 1148, a time when Gothic design was popular across Europe. A key feature of Gothic Cathedrals was their elaborate stained glass windows, of which Merevale was well decorated. And while the abbey was only small, it played its part in British history; Edward III was born there in 1312.
The Abbey was decommissioned by Henry VIII in 1538, and shortly fell into ruin. The above example of a stained glass window was salvaged from the site, and depicts the 14th century lord, John de Hardreshull, and his wife. It was common at this time for important persons to add a panel of themselves to the local church, and so the stained glass became a kind of historical document, recording important events.
