Blok was probably the greatest Russian poet since Pushkin; although internationally less well known than Rilke and Valéry, he is of their stature and importance. He revolutionized Russian versification by making use of a purely accentual technique. He knew, as so few now know, that only the poetry of suffering – whether it is a poetry of joy or not – can be great. His own poetry, for which he burnt himself out, demonstrates this.
