Martin Puryear’s "Vessel." (Martin Puryear/Courtesy Matthew Marks Gallery)

One of the more celebrated artists to hail from Washington, Martin Puryear, 74, has become widely known for his sometimes enigmatic sculptures that blend traditional craftsmanship with serious intent and occasional whimsy.

One of Puryear’s most monumental sculptures, “Bearing Witness,” has stood like a four-story exclamation point at Federal Triangle in Northwest Washington for nearly 20 years. And “Big Bling,” a temporary installation that’s just as tall, opened this week in Manhattan’s Madison Square Park. More often, Puryear’s elegant, gallery-size creations in wood and stone are fraught with considerations of culture and self-examination.

This week, “Martin Puryear: Multiple Dimensions,” a major retrospective of his drawings and lithographs as well as several sculptures, opens at the Smithsonian American Art Museum. Here are some numbers about the exhibition.
