The Dahesh Museum specializes in art from which era?

The Dahesh Museum is dedicated to showcasing and preserving art primarily from the 19th and early 20th centuries. This period is significant for its diverse artistic movements and styles, including Romanticism, Impressionism, and other forms that emerged as artists broke away from traditional norms. The museum holds an extensive collection that reflects the evolution of art during this time, focusing on works that demonstrate innovative techniques and themes that were prevalent among artists of that era.

While other options mention different historical periods, they do not align with the museum's mission or the scope of its collection. For instance, the 21st century embodies contemporary works that represent a vastly different artistic landscape, and the medieval period refers to an era that predates the museum's focus. Similarly, the 18th century, while important in art history, is outside the primary time frame that the Dahesh Museum specializes in. Hence, the selection of 19th and early 20th centuries accurately captures the essence of the museum's offerings.
