The Hood’s collections are drawn from a broad range of cultures and historical periods and represent a remarkable educational asset for both Dartmouth and the communities of the Upper Valley region of New Hampshire and Vermont. Among the museum’s most important holdings are six Assyrian stone reliefs from the palace of Ashurnasirpal II (about 900 BCE) and the remarkable fresco by José Clemente Orozco titled "The Epic of American Civilization" (1932–34), which is now a National Historic Landmark. The 67,000 objects in the museum’s care represent the diverse artistic traditions of six continents, including, broadly, Native American, European and American, Asian, Aboriginal Australian, African, and Melanesian art.
