Art is used as a form of expression. Greek artists included the ideas of reason, moderation, balance, and harmony, because it was what they believed in. The Greeks often glorified the idea of being useful, peaceful, and living in simplicity, which would explain why their art work was influenced by it.
In the work Still Life Parrot the more sharp tip of the parrots wing, beak, and the edges of the watermelon slice contrast nicely with the rest of the shapes in the artwork, which are mostly round and spherical. This makes it more dynamic and interesting to look at. The shading on the fruits, especially on the inside of the orange, help it to appear more 3-dimensional and give it life. The red of the watermelon slice, and some of the other fruits are directly opposite on the color wheel of the green fruits in this still life painting.
