For viewers who are on the fence about this self-mythologizing American artist, who died, in 1997, in Cairo, the brace of marble sculptures here offers a chance to see Byars at his most Apollonian and least indulgent. A stack of ten cubes, taxed with the title “The Figure of Death,” has the austere magnetism of an Alpine massif. A concave, eight-foot-tall totem in the shape of a half-moon conveys the simplicity and solemnity that Byars always aimed for but, with his gold lamé suits and shamanistic insinuations, too often failed to achieve. Through Sept. 3 (Werner, 4 E. 77th St. 212-988-1623.)
