HI i'VE READ THAT CLASSIC GREEK (bloody caps lock!) sculpture portrayed cultivated heroes and gods with small phalluses and satyrs with gross lkarge ones, symbolizing base animal instincts.
therefore the more elevated subjects couldn't be shown with large (uncouth, animal cocks) so all the athletes, warriors etc always were small and "neat" not through any prurience but through a different value system to ours.
These styles were passed down through Rome and into the Renaissance, although the reasoning was probably lost to them.
But who knows what went on in the twisted minds of Renaissance Catholic Cardinals.
ps I'm art trained and cock obsessed, but it was M's DAVID'S hands and tendons that left me breathless.
I've done art anatomy and drawn countless naked men, but gosh it looks like I'm going to have to raid a cemetery and cut up a corpse if I'm going to improve.
Thanks for this thread, too.
