joined with the Peredvizhniki (The Itinerants), and took on important commissions, among them portraits of grand duke Pavel Alexandrovich, (1897, Tretyakov Gallery), S.M. Botkin, 1899, and Felix Yusupov, 1903 as well as Princess Olga Orlova (these in the Russian Museum in St. Petersburg). In these truthful, compositionally skillful, and picturesque executions in the grand manner, Serov consistently used linear-rhythmic drawing coupled with decorative color combinations. At the same time, he developed a contrasting direction: he frequently produced intimate, heartfelt, chamber portraits, mainly of children and women. In portraits of children Serov aspired to capture pose and gesture, to reveal and emphasize a spontaneity of internal movement, sincere cleanliness and clearness of attitude of the child (Children, 1899, Russian Museum; Mika Morozov, 1901, Tretyakov gallery). Serov frequently called upon various graphic techniques—watercolors, pastels, lithographs and so forth. Figures in Serov's portraits gradually became more and more graphically refined and economical, particularly during the late period (Vasily Kachalov, 1908, Tamara Karsavina, 1909; numerous figures from Ivan Krylov's fables, 1895–1911). From 1890 to 1900 Serov produced many landscape compositions on country themes, in which the artistic direction took a romantic turn. Marriage and family Serov married Olga Trubnikova in 1889. His wife and his children were the subject of many of his works. Notably, his painting Children was of his sons Yura and Sasha. His children were Olga, Alexander(Sacha), George (Yura), Michael and Anton. Late work During his late period, which began in 1900, Serov was a member of "The World of art", an influential Russian art association and magazine which grew, in part, out of dissatisfaction with the Itinerants movement. At the start of the 20th century, Serov was at a stylistic turning point: features of impressionism disappeared from his work, and his modernistic style developed, but the characteristic truthful and realistic comprehension of the nature of his subjects remained constant. In the early 20th century Serov created heroic portrait images; within the genre of the fashionable portrait, Serov focused on the dramatic depiction of creative artists, writers, actors, and musicians of import: Maxim Gorki's portraits (1904, A.M. Gorki's museum, Moscow); Maria Yermolova (1905) and Feodor Chaliapin (charcoal, 1905), both in the Tretyakov Gallery; and Helena Roerich (1909). Serov's democratic beliefs were clearly shown during the Revolution from 1905 to 1907: he depicted a number of satirical figures exposing chastisers.
