Richard Hart, Archaeological Journal (1845)
“ In applying this catalogue to the interpretation of ancient art, abstract as much as possible the emblem from its unimportant circumstances, making a logical distinction between the proprium and the accidens. Even in cases where they rigorously adhered to the ancient symbolism, the painters varied considerably in the detail. Of this many examples could be given. The same martyr is sometimes represented as transfixed with arrows, and sometimes he bears an arrow in his hand. ”
