St Mark - The Lion

Detail from a window commissioned to celebrate the 150th anniversary of St Mark's Church in Swindon.
A detail from a large and spectacular window by Martin Travers over the main alter in St Mark's Church (the Railway Village, Swindon).
Apparently the lion represents St Mark in Christian iconography. In this church built for the first railway workers in Swindon, the symbol of the lion is hidden all around the the church.
