In other words, they get to me.
Foremost on that front is the 16th/17th century artist Frans Snyders. The man took chaos and turned it into a visual symphony. He grasped the real world and showed it to us at it's most brutal; men killing animals, animals killing animals, animals engaged in hideous social cacophonies rarely witness in real life...yet somehow more true than life. His specialty was excess. If there was a table with butchered game, it had corpse after corpse of a dozen or more types of animal and bird. If an animal was being attacked, it was locked in a terrifying, frenzied melee'! I find that overwhelming hyper-reality invigourating. There is nothing staid about Snyders' work. Honestly, I find it difficult to look at his paintings for too long, as they tap into something bestial inside me. It's unsettling.
On the other hand, he has a fondness for paintings of hogs, which, as a former Banjo player, I find highly amusing.
