Ut Pictura Poesis (as painting, so is poetry) is a centuries old philosophy of painting which finds beauty in ordinary subjects and elevates them through the act of painting.
Painting is as noble as any human action because it imitates human action in nature.
We're made so that we love
First when we see them painted, things we have passed perhaps a hundred times,
Nor care to see:
And so they are better, Painted
Better to us, which is the same thing
- Robert Browning "Fra Lippo Lippi" 1855
