Pushkin and Alexander Griboyedov.Lermontov lived a short but very interesting and eventful life. Turning to his biography, it is possible to find a lot of very interesting facts about the life of the poet, as well as the history and origin of its kind. So, for example, we know that the genus Lermontov came from Scotland, and dates back to the mythical bard-prophet Thomas the Rhymer. In 1613, one of the members of this genus was captured in the capture of Russian fortress and White, among others, the so-called Bielski Germans entered the service of the Tsar of Muscovy. He moved to Orthodoxy and became, under the name Zhivago, the founder of Russian noble family Lermontov. Mikhail knew about their no Russian roots, and dedicated the poem "Desire", he wrote in 1831, his Scottish ancestors. Lermontov featured mad passion for the works of Pushkin. In his poems, novels he sometimes imitated his idol. Lermontov and Pushkin life was like. Duelist, bully and a mocker. The poem "Death of a Poet", written immediately after the murder of Pushkin, shows all the love which the poet had for genius. Symbolically, Lermontov, like his idol Pushkin was killed in a duel, slain enemy bullet. It seems to me that Lermontov, in the last moments of life was proud that he died as great Pushkin.The news of the death of Lermontov different was perceived in society. Some said, "there he and the road" ... the emperor himself said, "Lord, received the news that the one who could replace us Pushkin, killed." Whatever they say, I find in the works of some of the fundamental Lermontov. The issues raised by them in the novels - is the perennial problems of society, and poems of the great poet imbued with a high sense and profound meaning, are easily read and remembered for a long time
