Like his colossal humanoids made of rough-hewn blocks of stone at Rockefeller Center in 2013 or his colorful rock stacks located outside of Las Vegas, Ugo Rondinone’s towering sculptures at Gladstone Gallery offer a transformative experience. Titled ‘nuns + monks,’ the three figures are scaled up bronze versions of stones broken in ways that resemble figures in voluminous ecclesiastical garments. Rondinone explains that nuns and monks exist as ‘vessel and beacon, human body and mystical source,’ and therefore represent the possibility of new metaphorical interpretation. (On view in Chelsea through June 18th. Masks and social distancing are required.)
