Imagine painting a masterpiece that you knew no living person would ever see, sealed inside a stone tomb forever. Now imagine painting a massive picture on the outside of a city building for thousands of people to see every single day.
Artists in different eras and cultures created art for completely different reasons. To understand their work, we look at the artwork's purpose (why it was made) and its effectiveness (how successfully the artist used materials, symbols, and emotions to achieve that goal).
What makes two artworks from opposite sides of history look so totally different?

Two Artworks, Two Worlds

Let's compare an ancient Egyptian tomb painting from over 3,000 years ago with a modern Mexican public mural from the 20th century. An artist's medium is the material they use to create art, like mineral powder, plaster, or oil paint.
How do we figure out whether an artist actually succeeded at their job?

Comparing the Purpose

The Egyptian tomb painter wanted to ensure eternal peace for the deceased. Because of this spiritual purpose, they followed strict rules: drawing figures from their clearest angles so the gods could recognize every body part.
In contrast, 20th-century Mexican muralists like Diego Rivera wanted to teach history to everyday people who might not know how to read. Their public purpose required giant sizes, bright colors, and dramatic emotions that anyone walking down the street could feel immediately.
So how do we measure how well each artist pulled off their goal?

Evaluating Effectiveness

An artwork is effective when its artistic choices support its main goal. Artists use symbols, which are pictures or shapes that stand for bigger ideas, to send clear messages.
