I love 19th-century Western art. Zach, not so much. The only painting we can both agree on, that is wonderfully awe-inspiring, is Caspar David Friedrich's Monk by the Sea. Are you familiar with this painting?
It's sublimely haunting and contemplative. I would love to see this one in person. If you've never seen it before, you can be glad you've seen it now (albeit on a computer screen)!
