анализ стихотворения ахматовой пусть кто-то еще отдыхает на юге:
1)история создания стихотворения
2)о чем стихотворение
Пусть кто-то еще отдыхает на юге
И нежится в райском саду.
Здесь северно очень — и осень в подруги
Я выбрала в этом году.
Живу, как в чужом, мне приснившемся доме,
Где, может быть, я умерла,
И, кажется, тайно глядится Суоми
В пустые свои зеркала.
Иду между черных приземистых елок,
Там вереск на ветер похож,
И светится месяца тусклый осколок,
Как финский зазубренный нож.
Сюда принесла я блаженную память
Последней невстречи с тобой —
Холодное, чистое, легкое пламя
Победы моей над судьбой.
1956, Комарово-
