Badovici cultivated relations to European avantgarde magazines like Wendingen (Netherlands) and Cahiers d’Art (France, founded in 1926) of his friend Christian Zervos.
In this highly complex and avantgarde work, he anticipated many innovations made by modern European experimentalists such as James Joyce, Virginia Woolf, William Faulkner or André Gide.
