On the oak roof boss of the 15th century of Thrownleigh, you can see the mysterious sign of the three hares. The three hares is a circular motif appearing in sacred sites from the Middle and Far East to the churches of Devon, England (as the "Tinners' Rabbits"), and historical synagogues in Europe. It is used as an architectural ornament, a religious symbol, and in other modern works of art or a logo for adornment (including tattoos), jewelry and a coat of arms on an escutcheon. It is viewed as a puzzle, a topology problem or a visual challenge, and has been rendered as sculpture, drawing, and painting. They are known as the "Tinners' Rabbits". Local writers described them as the mark of tin miners giving thanks for rich finds by rebuilding or enlarging churches.
