Di Suvero, Mark (1933- ), American sculptor, whose massive works are constructed from timber, old tires, scrap metal, steel girders, and other industrial materials. His style was influenced by such abstract painters as Franz Kline, an American, whose blunt energetic strokes and thrusting lines are echoed in di Suvero's cantilevered three-dimensional works. His bold constructions are characterized by oblique lines and strong diagonals, and they are set in angular, tense arrangements that often appear to be precariously balanced, although they are in perfect equilibrium. A pervasive playfulness is also evident in his constructions, as if they were intended to be enjoyed as gargantuan toys.
