"Generally, one may characterize the works of the late sixties as being subject to a relentless paring down to the essential elements of painting. The coltish whimsy of the early works is gone, and in its place is a grave monumentality. Movement is slower; forms are larger and simpler. Fewer decisions are made, but greater deliberation goes into each decision."
Barbara Rose, Frankenthaler, New York 1972, pp. 99-100
