Carl Andre, Grecrux (1985). Via Art Rabbit
“For his sculpture, Grecrux, Andre used 53 travertine blocks to create a Greek cross, or cross quadrata, in which each of the four extended lines are of equal length. This geometrical sculpture was one of Andre’s earliest works in travertine, expressing the tangible relationship between sculpture and space. Andre did not see his work as a vehicle for a metaphor, rather, his sculptures represent structure—an object taking up physical space with a geometric form.” via
