 Aderca's other activity, as a translator, produced versions of Romain Rolland's "The Humble Life of the Hero" and "The Precursors" (both 1924), as well as of texts by Stefan Zweig (1926).He also translated Karel Čapek's "R. U. R." (1926), and Barbusse's "Under Fire" (1935).Aderca's advocacy of Lovinescu's ideas, with its critique of didacticism and political command in art, was the connecting element of the essays he published in 1929
