ENThe period from the end of the 6th decade and the 7th decade is the time when the face of modern Lithuanian painting has been formed. One of the most significant factors of the process was the revival of painting principles of the artists of the interwar group ARS which was accepted as Lithuanian painting tradition of the period, on no condition. The ambivalence (of the tradition of the artists of ARS and its relation to the novelties of painting that emerged in the 6th and 7th decades are analysed in the article. The period discussed is being estimated as the development and expansion of expressionistic tendencies in Lithuanian painting reaching as far back as the 4th decade of the 20th century and, conditionally, as the end of such stylistics because of new views themes and motifs which emerged in paintings. Throughout the end of the 6th decade and the 7th decade Lithuanian painting has been in touch with European modern art (impressions, abstractionism, neorealism) which in combination with the tradition of local art has formed an individual quality of art and has been influential in the subsequent development of Lithuanian painting.
