S. Baring-Gould, The Legendary History of the Cross
“ Tau Cross: “The Cross is our crucified Lord in person; ‘Where the Cross is, there is the martyr,’ says St. Paulinus. Consequently it works miracles, as does Jesus Himself: and the list of wonders operated by its power is in truth immense. By the simple sign of the Cross traced upon the forehead or the breast, men have been delivered from the most imminent danger. It has constantly put demons to flight, protected the virginity of women, and the faith of believers; it has restored men to life, or health, inspired them with hope or resignation. ”
