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.
