For additional reading, let me highly recommend George Ferguson’s, Signs and Symbols in Christian Art. If you are an artist looking for many symbol variations, Heather Child and Dorothy Colles’ book, Christian Symbols, Ancient & Modern is excellent. The best place I have found online to purchase older, out-of-print Christian symbols books is www.alibris.com.
