What type of artwork combines several different styles or sources?

The term that best describes artwork that combines several different styles or sources is "pastiche." Pastiche involves the imitative use of various artistic styles, genres, or elements from diverse sources, often celebrating or paying homage to them. This technique allows artists to create unique works that acknowledge and reinterpret influences from different art movements, cultures, or historical periods. It can result in a rich tapestry of visual language that reflects the complexities of artistic expression.

Original artwork primarily refers to pieces created from an individual artist's unique vision without directly imitating or drawing from other art forms. Classical artwork typically pertains to art forms that align with ancient traditions, often characterized by idealized forms and adherence to principles established in earlier art, such as Greek or Roman styles. Realistic artwork focuses on accurately depicting subjects as they appear in real life, emphasizing detail and lifelike representations rather than the blending of styles and sources. Thus, pastiche stands out as the most accurate descriptor for the combination of artistic elements from various influences.
