45 44 a ChurCh window not far from the Isle of Man A typical piece of church window masonry is shown opposite. It is a very beautiful design and the sort of thing that can be seen in many churches. There are a number of ways of drawing it but see if you can follow its construction from the diagram below which begins with the enclosing circle. Notice how every detail is defined by the geometry. Draw a large circle and divide it into six. Draw a large triangle and fit a circle inside it to give the centres of three touching circles. Notice how these do not quite touch the outer circle. A small circle which represents this then gives the width of the stone tracery itself. This simple principle can be easily extended. The design speaks of the implicit trinity in unity.
