Art history is the study of visual art and its development over time. It explores how different cultures and societies have expressed themselves through various forms of art, such as painting, sculpture, and architecture. By examining works from different periods, like the Renaissance or Impressionism, we can understand the ideas, values, and techniques that shaped artistic expression. This field also looks at influential artists, such as Vincent van Gogh and Frida Kahlo, and how their unique styles contributed to the evolution of art. By analyzing these works, art historians uncover the connections between art, culture, and history, revealing the stories behind each piece.
