“The morturary chapel at Compton in Surrey, England, was designed by Mary Seton Watts in 1895 and executed by local people using local materials. Its basic design is Byzantine: it is a drum with a domed roof. Into this is set a Greek or Celtic cross which protrudes as four gables…The circle is the prehistoric sign of eternity and the cross the sign of salvation…The Celtic imagery draws parables from nature to address the deep uncertanties that related to the purpose of life and the emotions that are prompted by the inevitability of death…The Path of the Just is traced in the frieze on the outer walls, each section representing the spirits of hope, truth, love and life…A phoenix reises from the flames, life from the throes of destruction, resurrection from the grave. This…chapel...explicitly registers despair and locates it with a narrative of purpose that is varied enough to engage a wide range of human conditions...Art is not so much an activity at the disposal of the Christian faith as the standard way in which religious faith is expressed.” [from: The Art of the Sublime: Principles of Christian Art and Architecture, by Roger Homan, 2006, p. 37-38.]

In this terracotta frieze from the Watts Chapel in Compton, England, the figure to the far right is The Spirit of Truth. Below her are an owl and keys, both symbolic of wisdom/truth. The chapel was designed and built by Mary Fraser Tytler Watts, a symbolist craftswoman, designer, and social reformer. For the Watts Chapel, she set up a pottery-making operation and employed local workers, thereby advancing the social, economic, and spiritual lives of the less advantaged members of her community. 

"The design itself is an amalgamation of inspiration, every aspect having symbolic meaning. The Circle of Eternity with its intersecting Cross of Faith is from pre-historic times and symbolises the power of redeeming love stretching to the four quarters of the earth. The dome is traditionally seen as emblematic of heaven, the four panels on the exterior containing friezes symbolising the Spirit of Hope, the Spirit of Truth, the Spirit of Love and the Spirit of Light."
