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 the blue polar foxes shine bright in my ways
As they glisten in 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 lips 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 speech 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 Russian 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 can live just 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 venerate your ribs becoming Russian soil
Reverberating through the speechless Universe.
Joseph Brodsky's "Letter to a Roman Friend (in the spirit of Marcus Valerius Martialis )".
Unfinished translation by Michael Efroimsky
Wind and waves are overlaying one another.
Autumn yields metamorphoses everywhere.
Season-caused transfigurations, Postume brother,
Touch me deeper than my lady's new ware.
. . .
I am sending you some volumes, Postume brother.
How's Rome? - Friends with steel in their pockets?
How's the Caesar? Still intriguing, I gather...
Still intriguing and feeding to a surfeit.
I am sitting in my yard. My lamp is burning.
No lass or friend or servant is around.
Just the company of insects gently droning...
No Princeps, no subjects, no crowd...
Here's an Asian merceant's grave, a shaft of marble.
He was modest, but persistent in his business.
He died swiftly of a fever. He had travelled.
To this land to get some cargo, not an illness.
Here's a legionnaire's tomb, a rugged ledger.
He had gloriously fought to Rome's avail.
Often could have been killed. Yet died he aged.
Even here, Postume, rules are doomed to fail.
. . .
From the tempest you are far, and from the Caesar.
No need to cringe, to rush, to dread the thunders.
All the governors, you say, are bloody stealers.
I prefer the bloody stealers to blood-mongers.
. . .
Sweat hetaera, let us quit negotiations.
You are not to stay alone in this sprinkle.
I shall cover you, but charging me sesterces
Is like sparing your roofing of a shingle.
Am I leaking through? - A puddle still is absent.
No puddle have I ever left behind!
When you find some one to be your husband.
He will be free to leak under the blanket
Days to come are less than those left behind.
By a tavern, once I heard an old slave utter
That a lot of ruins can be seen around.
Words of wisdom, though from a savage gutter...
From a hillside stroll, I brought a spray of blossom.
Here's a jug for it. I put some water there.
How's Lybia? - or where is it, Postume?
Whether are we still engaged in warfare?
Postume, our Proconsul has a sister.
Slim in waist, she otherwise is pretty ample.
You have slept with her. She has become a priestess.
Priestess, Postume. And is serving at a temple.
Come to share news and bread and plums and wine.
In the night, as heavens clear, dark and spacious,
I shall set for you a couch in the garden,
And shall tell you what they call the constellations.
Soon your friend, a devotee of composition,
Shall be subject to the ultimate negation.
Search the cache under the cushion. Requisition
All the money. Tender for the inhumation.
City walls shelter a house of ill fame.
Thither, thitherwards you ride your raven mare.
Pay the money, for which they entertain.
Let them now mourn me for the same fare.
Shivers running through the verdure of a laurel...
Dust enshrouding the sill of the fenestra...
Open doors... A bed and chairs - all forlorn...
The meridian sun infusing fading vestures...
The thalatta roars behind the hedge of pines.
By the promontory, a windward ship is beating.
On a cloven bench - a script by Plinius Gaius.
From a cypress' crown comes a blackbird's twitting.
