 Eugene Kolb published a flattering critical article on Aroch's work, and described his transition from Post-Impressionism to an emphasis on “constructed forms” and “simplicity of color.” His works from the middle of the decade show a tendency toward schematism and the deconstruction of the scene into geometric parts in the style of the Cubists.This phenomenon can be seen also in earlier works, such as “The Red Bus” (1944-1946), from his series “Bus in the Mountains.”

From 1956-1959, Arie Aroch served as the Israeli ambassador to Brazil.Concurrently, he served as Ambassador to Venezuela (1957 - 1958).
