Still another poet was Afanasy Afanasievitch Shenshin, who wrote under the name of Fet. Born in 1820, he began to write at the age of nineteen. About that time, on entering the Moscow University, he experienced some difficulty in furnishing the requisite documents, whereupon he assumed the name of his mother during her first marriage--Fet. He reacquired his own name, Shenshin, in 1875, by presenting the proper documents, whereupon an imperial order restored it to him. From 1844 to 1855 he served in the army, continuing to write poetry the while. Before his death, in 1892, he published numerous volumes of poems, translations from the classics, and so forth. Less talented than Count Alexei K. Tolstoy, Apollon Maikoff, and other poets of that school, his name, in Russian criticism, has become a general appellation to designate a poet of pure art, for he was the most typical exponent of his school. Most of his poems are short, and present a picture of nature, or of some delicate, fleeting psychical emotion, but they are all filled with enchanting, artistic charm. His poetry is the quintessence of aesthetic voluptuousness, such as was evolved on the soil of the sybaritism of the landed gentry in the circles of the '40's of the nineteenth century. The oldest of all these worshipers of pure art was Feodor Ivanovitch Tiutcheff (1803-1873). At the age of seventeen he made a remarkably fine translation of some of Horace's works. He rose to very fine positions in the diplomatic service and at court. Although his first poems were printed in 1826, he was not widely known until 1850-1854. His scope is not large, and he is rather wearisome in his faultless poems. The majority of them are rather difficult reading. A poet who did not wholly belong to this school, but wrote in many styles, was Yakoff Petrovitch Polonsky (1820-1898).[26] Under different conditions he might have developed fire and originality, both in his poems and his prose romances. His best known poem is "The Grasshopper-Musician" (1863). He derived his inspiration from various foreign poets, and also from many of his fellow-countrymen. Among others, those in the spirit of Koltzoff's national ballads are not only full of poetry and inspiration, art and artless simplicity, but some of them have been set to music, have made their way to the populace, and are sung all over Russia. Others, like "The Sun and the Moon" and "The Baby's Death" are to be found in every Russian literary compendium, and every child knows them by heart.
