Gustav Klimt’s The Kiss (1907-1908) and Egon Schiele’s Cardinal and Nun (1912)
In 1907, Egon Schiele sought out Gustav Klimt, who generously mentored younger artists, and he took a particular interest in the gifted young Schiele, buying his drawings, offering to exchange them for some of his own, arranging models for him and introducing him to potential patrons.
Klimt invited Schiele to exhibit some of his work at the 1909 Vienna Kunstschau, where he encountered the work of Edvard Munch, Jan Toorop, and Vincent van Gogh among others. Schiele began to explore not only the human form, but also human sexuality. At the time, many found the explicitness of his works disturbing.
