Poet of tragic fate, О. Мандельштам did not consider itself a poet tragic. He has the landscape and love lyric poetry painted in the most tender water-colour tones, there are the verses, pierced by the easy "Petersburg" humour, but there are arriving at high dramatic incandescence verses about suppression of man the state (thus a poet with identical hostility talks both about pre-revolution and about bolshevist Russia). For him only measure and a point of counting out is a man that is original higher embodiment of Nature and History. This idea passes through all work of poet. The most complete corps of poems of О. Мандельштама is presented in a book. Vast comments will help to enter the difficult world created by one of the glorified poets of the Silver century.
