Rodin's "The Thinker": I've loved this piece all of my life. I think it's one of the most beautiful depictions of the human form; equally capturing the physiological, intellectual, emotional and spiritual essence of a human being. Auguste Rodin was an absolute genius.
Miguel de Cervantes' "Don Quixote": I was that nerdy kid who loved to read classic literature in elementary school. This novel was one of my favorites then...and still is. The story combines two of my literary passions, heroism and insanity, in such a way that you're not often sure which is which...totally awesome.
