What is a green ‘tau’? Tau τ is the Greek letter similar to the English T. Tau itself developed from the Phoenician letter Tāw X (from which the Hebrew letter Tav ת is also derived). In ancient times, tau was used as a symbol meaning eternal life or resurrection. In Hebrew tav means mark and this was the sign marked on the foreheads of those who lamented their sins (Ezekiel 9:4). For early Christians tau became an apt symbol of the cross on which Jesus was crucified.

Francis of Assisi used the tau as his mark when signing his letters and other writings. The tau cross, often made of wood, is worn by many Franciscans across the world. Francis is widely known as the saint who spoke with the birds, and to the hungry wolf in Gubio – he worked out a deal between the wolf and the people of Gubio such that they could live together in harmony. Francis was the author of the canticle ‘Brother Sun, Sister Moon’ – probably the first piece of literature written in Italian. Francis understood that everything in creation had been made by God and was deserving of equal love and respect and should be treated as brother or sister. In 1979 Pope John Paul II declared St Francis as the patron saint of ecologists, reflecting not only Francis’s love for all creatures, but also his intuitive understanding of the interconnectedness of the whole of creation. I therefore chose a green tau to represent my desire to live sustainably, protecting the earth.
