In the history of Bulgarian art, there are numerous forgotten artists. However, few of them present as intriguing a case as Petar Dachev. His work unfolded during a period of intense artistic transformation, and his pieces bear witness to a sensitivity toward the new visual ideas and cultural processes of the first half of the 20th century. The exhibition “The Petar Dachev Case,” organized on the occasion of the 130th anniversary of the artist’s birth, is yet another research project by the Sofia City Art Gallery aimed at rethinking established historical perceptions and restoring the more complex picture of Bulgarian art between the two World Wars. The project brings together over 200 works that trace various aspects of the author’s creative and personal biography.
