Considering who the paying master was, that alone was cause for caution. I feel somehow the artists yesterday as today seem very up on occult knowledge and the symbols used. I like to think many tried to put as much in their paintings as they could get away with. A lot of it turns back to intent and integrity.
As much as some Christians are insulted by the opening ceremony, in my understanding the whole olympics affair was always a Bacchanalia festivity.
