Goethe began work on Faust, and Egmont, another tragedy before being invited to join the government of Weimar. His interest in the classical world led him to leave suddenly for Italy in 1786 and the Italian Journey recounts his travels there. Iphigenia in Tauris and Torquato Tasso, classical dramas, were written at this time. Returning to Weimar, Goethe started the second part of Faust, encouraged by Schiller. In 1806 he married Christiane Vulpius. During this late period he finished his series of Wilhelm Master books and wrote many other works, including The Oriental Divan (1819). He also directed the State Theatre and worked on scientific theories in evolutionary botany, anatomy and color. Goethe completed Faust in 1832, just before he died.
