SFMOMA, Part 43: Floor 5, Calder, Kelly, LeWitt: Fundamentals of Form.
The shadow is doing half the work. A square of painted brass grid hangs a few inches off the gallery wall, and the squares inside it — one unit, two units, three, then back down: 1 2 3 2 1 — throw a second, softer drawing onto the plaster behind them. Eleven years after LeWitt's first wall drawing, the idea had learned to cast a shadow.
Sol LeWitt's Wall Structure, No. 4 (1 2 3 2 1), 1979, is on view on Floor 5 as part of Calder, Kelly, LeWitt: Fundamentals of Form, in Reimagined: The Fisher Collection at 10. Painted brass, 37 × 37 inches, from the Doris and Donald Fisher Collection. Entry is included with general admission; SFMOMA, 151 Third Street, is open Mon–Tue and Fri–Sun 10 a.m.–5 p.m., Thu noon–8 p.m., closed Wed.
The easy reading is: a counting exercise, minimalism's most famous abacus. But the subject is sharper than that. The sequence 1-2-3-2-1 is a palindrome — it reads the same forward and backward, a sentence that returns to its own beginning. LeWitt's wall structures of the late seventies live exactly at the seam where drawing put on weight and became sculpture: open grids bolted to the wall, obeying the flatness of the wall while refusing to be flat. This one is not math. It's syntax. A complete statement, made of nothing but structure, that says itself and then takes itself back.
1974: 122 ways to not finish a cube
To feel how radical this restraint is, look back five years. In 1974 LeWitt produced Variations of Incomplete Open Cubes: 122 wooden skeletons, each one a cube missing some of its edges, systematically working through every permutation of incompleteness. It's an absurd, magnificent project — the definition of a cube exhausted by everything a cube can fail to be. The wall structures are what came out the other side of that exhaustion. Where the incomplete cubes multiplied possibilities to the point of delirium, the 1979 wall structures compress them: a single flat field, a single rule, a single palindrome. The earlier work asked how many ways an idea can break. This one asks whether an idea can be whole.
1979: numbers that behave like words
The painted brass matters more than it seems. Brass is a metal with a memory of monuments — doorknobs, plaques, engraved names — and here it holds a sequence with no content at all. 1 2 3 2 1. No subject, no verb, just rise and fall. But stand in front of it for a minute and the sequence starts behaving like music: exposition, development, return. Like a sentence: assertion, complication, resolution. LeWitt always insisted his systems were irrational choices made rationally — "the idea becomes a machine that makes the art" — but the machine kept producing things that felt, unmistakably, like feelings. A palindrome is the shape of a sigh.
The show, again
In the Floor 5 gallery this piece hangs in conversation with the wall drawing from 1968 and the prints of cubes that fan out across the room, and the effect is cumulative: you start seeing the whole room as one long sentence LeWitt spent forty years writing. The wall structure is the clause where he briefly stopped drawing and started building. Walk past it slowly and watch the brass shadow slide against the graphite-gray wall behind it — the work is the grid, but the work is also the ghost the grid throws. Two drawings for the price of one, and neither of them is the brass.
I stood there counting under my breath — one, two, three, two, one — like a kid on stairs, and the museum guard didn't even look up. He'd heard it before. 🌁
