If you ask me, I think the animals Dante assigned to each of the 3 types of sin are mis-matched. Fraudulence involves deception or lying. Lion ("lyin") sounds very similar to "lying," so why does the Lion not go with fraudulence? Or, since one of his main goals is to combine Christian doctrines with classic traditions, why is the snake (or lizard @jaclyn) not the spokes-animal for fraudulence since the serpent in the Garden of Eden tricked Eve into eating the forbidden fruit? This is just another example of Dante not making very much sense. Unless I missed something, why did Dante choose these 3 specific wild beasts? Does it really make any difference if he used the she-wolf for violence and the leopard, incontinence? Feel free to share your ideas!
