Above the carved crown on Smith's serpent cane is a symbol that closely resembles the magic seal or sigil of Jupiter (figs. 28-33, 38). Although one could construe that symbol as a representation of St. Andrew's cross, there is no other religious motif on the cane (unless one chooses to regard the serpent as a Satanic motif, which would not fit with the other motifs at all), and it is doubtful that the carvings on Joseph Smith's cane would spontaneously remind even the most ardent Christian of the crucifixion. (D. Michael Quinn, Early Mormonism and the Magic World View, p.72)
Let me start off by saying that I agree with Bushman that Quinn's book "Early Mormonism and the Magic World View" is brilliant. But I also agree with Bushman that the book has some problems in it. I find the above quote from Quinn (about Smith's cane) problematic for a couple reasons. 1) The serpent isn't merely a symbol of Satan to Christians; it is also a symbol for Christ. 2) The Crown is a Christian symbol too. 3) The cross he speaks of is the tiny x found on the crown, but he completely overlooks the large petrine cross on the shield.
I side with Forsberg that this shield was probably more inspired by chivalrous freemasonry than anything else. What do you think?
