Fyodor Ivanovich Tyutchev (December 3, 1803 - July 27, 1873) was one of the great Russian poets. He wrote about four hundred poems in Russian and French. His favourite themes are chaos and the cosmos, day and night, human beings and nature. Tyutchev was strongly influenced by German romanticism. His love poems dedicated to E.A. Denisyeva were compiled in a "Denisyevski cycle", which depicts love as a great tragedy.
