Multiculturalism defines us in so many ways these days. President Barack Obama softens diplomatic relations between the United States and Cuba, and within weeks, Teatro Dallas is presenting a terrific play about Cuban poet Nicolás Guillén titled Poetry Dances.

On May 15, the Dallas Museum of Art recorded yet another landmark by opening its first exhibition devoted exclusively to Andean art, in a show titled “Conquests of the Andes/Los Incas y las Conquistas de los Andes.”

It consists of more than 120 objects that explore “the dynamic nature of state expansion and imperial conquest through Andean visual arts.” As with Poetry Dancesat Teatro Dallas, the DMA show is presented in both English and Spanish.

Museum director Maxwell Anderson credits the show with focusing “on the impressive, complex societies of western South America, those cultures that developed across the Andean highlands and desert coast for thousands of years prior to the Spanish conquest.”

It’s also the first show curated by Kimberly L. Jones, the museum’s curator of the arts of the Americas. Jones cites the Huari tunic, on view for the first time, as a standout. She estimates that it would take six to nine miles of thread and six to nine months to re-create the Peruvian tunic, which is dated to A.D. 850 to 950.
