John Baldessari (b. 1931)
The artist as shaman or alchemist proves to be a tedious fraud. In "Time/Temperature" (1972Ð73) a small hourglass and thermometer measure properties that are otherwise invisible. Like the camera, these are indexical instruments, but where the camera would ordinarily be taken for granted, these devices seem self-evident.
