Ахматова. Поэма без героя

From Alla Demidova's book "Akhmatova Mirrors": "When I began to decipher the "Poem without a hero", the more I found doubles in it, which, in turn, bifurcated and so on — to infinity (the same thing happens if you approach the wall of the mirror hall with a mirror and see in it an infinite a series of reflections), the more clearly I understood that it was probably not necessary to literally decipher it. Specific persons are not so important in the "Poem", the fragrance of time is important, because, among other things, a huge layer of culture of an entire epoch has entered into the "Poem", which for many young people today has become a long-past history."
