Won a name for himself primarily as a sculptor. Initially adhered to impressionism (a series of portraits of the family von Anrep, including the artist's B. B. von Anrep; gypsum, 1907, Russian Museum), developing in parallel a distinctive modernist style that transforms the form in generalized symbolic compositions. Expressive painted their works (usually made from plaster or wood), seeking to revive the bright sculptural polychromy of the middle Ages and Renaissance (the bust of Leonardo da Vinci, 1906, Tretyakov gallery; a Noble boyar (Marfa Posadnitsa), 1910, Russian Museum). Engaged in artistic porcelain. Continued to work as a master of portrait sculpture. Often referring to the grounds of national antiquities, became one of the brightest representatives of a modernist "Russian style". Rewrote the Slavonic Word about Igor's regiment, and decorated it with their ornaments and illustrations (1900-1906, Tretyakov gallery). Successfully acted as a painter and set designer (sketches of scenery for the Opera snow maiden by N..Rimsky-Korsakov, Maryinsky theatre, 1910; Russian Museum and Tretyakov gallery). Medieval iconography found in his art a new colorful and rhythmic dynamics and expression.
