Beginning in 1910 he painted primarily in a Cubist style, strongly influenced by Picasso and Braque, and produced works such as "Salome" (1911) and "Bathers" (1912). He also began to paint many still lifes around that time. In 1911, he edited several issues of Volné směry, promoting Cubism and publishing reproductions of works by Picasso. After both readers and the leaders of Mánes reacted negatively, he and others withdrew from Mánes and founded Skupina výtvarných umělců (the Group of Visual Artists), which was a Cubist-oriented group.
