In colonial South America, as in other colonized regions around the world, art was a powerful means of propaganda, a devious device employing pathos and the subtle (sometimes not so subtle) appropriation of indigenous culture to win over the hearts and minds of occupied populations. In the San Antonio Museum of Arts new exhibition Highest Heaven: Spanish and Portuguese Colonial Art from the Collection of Roberta and Richard Huber, on view through September 4, viewers can experience more than 100 18th-century colonial paintings, sculptures, furniture, ivories and silverworks. $15-$20, San Antonio Museum of Art, 200 W Jones Ave, (210) 978-8100, samuseum.org. Through September 4.
