Froebel’s Gifts were meant to be given in a particular order, growing more complex over time and teaching different lessons about shape, structure and perception along the way. A soft knitted ball could be given to a child just six weeks old, followed by a wooden ball and then a cube, illustrating similarities and differences in shapes and materials. Then kids would get a cylinder (which combines elements of both the ball and the cube) and it would blow their little minds. Some objects were pierced by strings or rods so kids could spin them and see how one shapes morphs into another when set into motion. Later came cubes made up of smaller cubes and other hybrids, showing children how parts relate to a whole through deconstruction and reassembly.
These perception-oriented “Gifts” would then give way to construction-oriented “Occupations.” Kids would be told to build things out of materials like paper, string, wire, or little sticks and peas that could be connected and stacked into structures.
In the 1980s, Serra found himself in the center of a public controversy over his piece titled Tilted Arc. While it was the government that approached him to create the work for downtown Manhattan’s Federal Plaza, the unveiling of the piece in 1981 was met with sharp criticism. The monumental sculpture was said to disrupt rush hour and the pedestrians who had to cut through the plaza daily. To the dismay of art lovers, the 120-foot-long, 12-foot-tall Tilted Arc was ultimately disassembled in 1989.
