Beauty is in the eye of the beholder. That's a bias perspective. People know what is beautiful and what is not. What did the sculptures and painters and other simple craftsmen think about when they put their hands to their mediums.
Love, Death, the endless March of time serving as the beat to which the two dance. These are things all artists have based their work on.
From the stone mason trying to have his work last long after he is gone to the basement wordsmith trying to capture how the love he has for his family is killing him. It's hard to describe a thing of beauty or the amount of time that goes into its development. I guess that's why they say beauty is in the eye of the beholder. Because only you and you alone can appreciate the work.
