A strain of mysticism is discernible in the floating colour fields of Mark Rothko’s glowing canvases

One of the curiosities of western art is that, until the 20th century, few visual artists were of Jewish ancestry. With odd exceptions such as the Pissarros and Simeon Solomon, the culture tended to produce verbal rather than visual imaginations. With the 20th century that changed. The important group of abstract expressionists that came out of New York after the second world war centred on at least two Jewish artists — Barnett Newman and Mark Rothko.

Both possessed a specifically Jewish imagination, and both narrowed down their pictorial language to forms that expressed mystical aspects of their ancestral culture and faith. In Newman’s case it was the ‘zip’, a thin vertical stripe in a colour field connecting Earth and Heaven. In Rothko’s work, after a long period exploring figurative, surrealist and mythical imagery, it was made up of horizontal colour fields floating and dissolving, placed above each other in unpredictable and absorbing proportions.
