Tolstoy was highly valued by Aleksander Blok and Valery Bryusov; Ivan Bunin, otherwise harsh in his comments on fellow writers, rated him very high; Velemir Khlebnikov mentioned him among his all-time favourites and, most surprisingly (according to Korney Chukovsky), Vladimir Mayakovsky knew his poetry by heart and often recited it in public. Both Tolstoy's poetry (the larger part of which has been transformed into classic romance) and his historical drama trilogy are regarded as an intrinsic part of the classic Russian literature of the 19th century.
