TRANSLATIONS FROM THE RUSSIAN POETRY
From Mandelshtam's Voronezh Notebooks.
Translation by Michael Efroimsky
For the roaring glory of ages to come,
For the sake of mankind's high tribes
I'm deprived of my place at the feast of my clan;
Of my dignity, honour and rights.
I am not of wolves' breed, but this wolfhound age
Stalked my path, and it clutched at my throat.
Let me sooner escape in Siberian steppes
Like a hat in a sleeve of a coat.
Not to stare the cowards and scum in the face,
Not to see bloody limbs in the wheel,
Let a blue polar fox shine bright in my ways
And enlighten the primeval chill.
Lead me into the night, to the Yenisey stream
Where pine trees reach for the sky,
For I am not a wolf by my blood or my breed,
And my tongue will be severed by lies.
________
In an early version of this verse, the final line used to read as
"And an equal will take my life." Later, Mandelshtam altered it.

More from Mandelshtam's Voronezh Notebooks.
Translation by Michael Efroimsky
May you keep and remember forever my voice for its taste of misfortune and smoke,
For its pitch and its tar, and for my humble patience and labour to death.
I wish the deep waters of Novgorod's wells were so dark, so silent and slow
That a seven-finned quivering star on the Eve of Christ Mass glistened faintly in their depths.
And for that, oh my Father, my Comrade, my Friend, and my stern and merciless Helper,
I, the outcast seed and the prodigal brother rejected as chaff from the Sovietwealth,
Will frame the wells in such rough, coarse-grained and tarnished log shelters,
That nomadic Tatars would be eager to sink Slavic princes in these wells.

Joseph Brodsky's dedication to Anna Akhmatova.
Translation by Michael Efroimsky
The fallen lock of hair, the execution sword,
The grain and the mill, the flames and the scripture --
The Lord remembers all, especially the words
Of pardon and of love, as prompted by His whisper.
They come through beats of pulse and shovels breaking ground,
Through bone-crashing crunch; and their pitch is rough.
As one lives only once, they have a stronger sound
When spelled by mortal lips, not whispered from above.
From lands across the seas, I greet you, mighty soul.
You found those words, and put the words to verse.
I greet your ribs of death, that are becoming soil
Reverberating through the speechless Universe.
