The guys a bit sneaky - he has a tool to use against the 'Lion' but the animal uses only what nature gave it. It could represent how man has learned to dominate the planet - not always in a positive way - using the tools he has created.This is probably utterly wrong, but it's the first thing that came into my head.
a man destroying an idol... a lion with wings??? not natural to me according to my knowledge of nature. Not that it is right to but they are fighting, nature may have given more physical strength to that creature but man with his intelligence finds a way to defend himself. One thing, I don't know who started the fight and why!!!LOL
History of the piece aside, it represents to me the equity of intelligence and physical strength.
The lion strikes at the man's heart (his inner strength) and legs (his support) to bring man to his four-legged level. The attack, though theoretically effective, exposes the lion's weakness.
Holding the lion's ear to steady his target and avoid its teeth, man strikes at the lion's exposed underbelly, showing his cunning for seeing opportunity to affect dominance, despite his inability to thwart the majority of the attack.
Based on the effect of the individual attacks, it is likely neither will survive. Thus, superior intellect does not trump physical strength, yet neither does the inverse apply.
