Line, Layer, and the Mapped Abstraction
Contemporary artists build abstraction out of real systems: Mehretu layers architectural plans under gestural marks that read as crowds, Xu Bing invents characters that look legible but say nothing, and Song Su-nam merges ink brushwork with color field painting.
Julie Mehretu starts each painting with something exact: plans of stadiums, airports, city grids, maps of migration routes. She traces these in thin lines, then adds vector-like marks that follow the plan's logic, and finally piles on dense, gestural strokes by hand. Nothing in that last layer is architectural anymore. It is pure motion. But because thousands of these marks accumulate at once, overlapping and pressing against each other, they read as a mass of bodies, a crowd caught mid-surge, even though the painting is technically abstract. The structure underneath gives the chaos a skeleton. In Stadia II, you can still find the bowl shape and seating tiers of a stadium ghosted beneath the storm of marks, so the energy above feels contained, aimed, almost roaring.
Xu Bing works from the opposite direction: instead of starting with real structure and burying it, he fakes structure that was never real. A Book from the Sky contains four thousand carved characters that look exactly like authentic Chinese writing, correct stroke order, correct proportions, printed and bound like a classical text. None of them exist. A reader fluent in Chinese walks in expecting meaning and gets nothing, which is the point: the installation questions whether authority and legibility are the same thing, and whether a system can look entirely trustworthy while being empty.
Song Su-nam sits between those two strategies and an older one. He keeps the ink, the brush, and the layered tonal washes of centuries-old East Asian painting, but drops the mountains, rivers, and scholars those tools traditionally depicted. What is left are broad, nonobjective fields closer to Western color field painting. The connection across this topic is material honesty used against expectation: real plans, real script conventions, real brush technique, each pushed until the system itself becomes the subject.
Key terms
- Gestural mark
- A brushstroke or line that records the artist's physical movement rather than depicting an object.
- Vector-like line
- A thin, directional line in Mehretu's work that follows the logic of architectural or map data.
- Color field painting
- A Western painting style using large, flat or layered areas of color with no recognizable subject.
- Pseudo-script
- Invented characters designed to look like authentic writing while carrying no actual linguistic meaning.
