Specializing in monumental sculptures, Heizer combines archaic stone and wood into feats of engineering. Brazil shows his interest in negative and positive forms, of presence and absence. The circles and their equivalent fractions are meant to depict the phases of the moon. Brazil is actually tiny when compared to Heizer’s earth-sculptures such as Levitated Mass where he perched a 340-ton granite megalith over a 456-foot-long slot constructed on the grounds of the LA County Museum of Art’s campus.
