St Andrew, Wissett, Suffolk
A 19th century representation of the medieval symbol of the Holy Trinity at Wissett CofE parish church. P stands for Pater ('father'), F for Filius ('son'), S for Spiritus ('spirit') and D for Deus ('God'). The lines linking the outher symbols read non est ('is not'), but the lines linking to the middle read est ('is').
