There is a lovely parish church in Long Melford, Suffolk. Called Holy Trinity Church, it is a fine example of the perpendicular gothic style, completed in about 1484. Some of its windows contain old pre-Reformation stained-glass. A tiny circular piece of stained-glass above the north door of the nave depicts something unusual. It is hard to see with the unaided eye, but if you can manage to see it properly, you will notice something interesting. Known as the Hare Window, it depicts the heads of three hares and three hare’s ears. Each hare appears to have the usual two ears, but each of the three ears on the glass are shared by a pair of hares.
Although unusual, the three hare motif is not unique to Long Melford. Another example, a ceiling boss with three hares sharing three ears can be found in the Chapter House of the Church of St Peter and St Paul in Wissembourg, France, and another on a bell at Kloster Haina near Kassel in Germany (http://www.chrischapmanphotography.co.uk/hares/page3.htm)
