Contributed by David Carrier / When the Metropolitan Museum of Art recently rehung its permanent European collection, the galleries devoted to Spanish art included an abundant selection of work from “New Spain,” as the vast Spanish empire was known during the colonial period. From 1521 to 1821, its territory included, among much more, what is now Mexico, Central America, and the US Southwest. Much of the art consisted of sacred baroque painting – arguably the first truly international art style. “Saints & Santos: Picturing the Holy in New Spain,” on view at the New Mexico Museum of Art, does it justice.
