Thermometer (Jasper Johns, 1959) An oil painting, painted by hand for you alone

The Physicality of Measurement

The canvas is vertically bisected by a central axis that houses an actual, functioning mechanical thermometer. This physical device divides the surface into two parallel panels of split canvas. On either side of this industrial instrument, thick applications of oil paint create textured, starburst-like shapes. The color palette consists of primary and secondary tones, including deep blues, bright yellows, bold reds, and accents of orange and white. Along the central vertical axis, stenciled numerical markings ranging from 10 to 120 run parallel to the thermometer's scale. These precise, factory-made numbers contrast with the heavy, impasto-like strokes of paint that move across the surface in chaotic, gestural patterns.

The Integration of Environment and Object

Created in 1959, this mixed-media assemblage moves beyond a static representation of temperature by incorporating a live measuring tool. Because the thermometer is functional, the work responds to the immediate climate of its exhibition space. As room temperatures shift, the mechanical indicators inside the gauge physically move, causing the composition to transform in real time. This integration ties the painted surface to the actual passing of time and environmental change. The work exists at a point of transition between the expressive, hand-applied marks of the artist and the standardized accuracy of industrial measurement.

Context within Neo-Dada

This piece belongs to the Neo-Dada movement, a period that bridged Abstract Expressionism with early Pop Art and Minimalism. By utilizing a found object—the thermometer—the work departs from purely two-dimensional painting to engage with three-dimensional reality. The use of recognizable, everyday symbols and mechanical tools reflects a shift away from the emotional grandiosity of earlier abstraction toward an investigation of how viewers perceive common objects. This approach challenges the distinction between fine art and utilitarian objects, as the physical climate of the gallery becomes an active component of the piece's visual state.
