IN THE HEART of old Poznan, the capital of Great Poland since ancient times, there is a public square called Rynek Glowny. The houses around it aren’t as lovely as those of Krakow, but they have been charmingly painted and there is a faded graciousness that wins the heart. The plaza came through World War II more or less intact, but the Communist government apparently could not bear the thought of so much wasted space. What use did it have? Public squares were for public demonstrations, and once the Communists had seized control on behalf of the people, public demonstrations would never be needed again. So out in the middle of the square they built a squat, ugly building in a brutally modern style. It sucked the life out of the place. You had to stand with your back to it in order to truly enjoy the square.

But we’d all seen the ugly building for so many years that we hardly noticed it anymore, except to apologize to visitors, ruefully remember the bad old days of Communism, and appreciate the irony that the occupants of such a tasteless building should include a restaurant, a bookshop, and an art gallery. And when the plague came and the city was so cruelly and suddenly emptied, those of us who could not let go of Poznan, who could not bear to eke out the last of our lives in the countryside, drifted to the old heart of the city and took up residence in the houses surrounding the square. As time passed, even the ugly building became part of the beauty of the place, for it had been part of the old crowded city now lost forever. Just as the toilets with little altars for the perusal of one’s excrement reminded us of the many decades of German overlordship, so this building was also a part of our past, and now, by its sheer persistence among us, a part of ourselves. If we could venerate the bones and other bodily parts of dead saints, couldn’t we also find holiness of a kind even in this vile thing? It was a relic of a time when we thought we were suffering, but to which we now would gladly return, just to hear schoolchildren again in the streets, just to see the flower shop once more selling the bright excesses of overcopious nature, spots of vivid color to show us that Poland was not, by nature, grey.

Into this square came the elephants, a group of males, making their way in what seemed a relentless silence, except that a trembling of the windows told us that they were speaking to each other in infrasound, low notes that the human ear could not hear, but the human hand could feel on glass. Of course we had all seen elephants for years on our forays out into the gardens of suburban Poznan—clans of females and their children following a matriarch, gangs of mature males hanging out to kill time until one of them went into musth and set off in search of the nearest estrous female. We speculated at first about where they came from, whether their forebears had escaped from a zoo or a circus during the plague. But soon we realized that their numbers were far too great to be accounted for that way. Too many different clans had been seen. On Radio Day we learned, from those few stations that still bothered, that the elephants had come down the Nile, swum the Suez, swarmed through Palestine and Syria and Armenia, crossed the Caucasus, and now fed in the lush wheat pastures of Ukraine, bathed in the streams of Belarus, and stood trumpeting on the shores of Estonia and Pomerania, calling out to some god of the sea, demanding passage to lands as yet unpossessed by the great stumpy feet, the probing noses, the piercing ivory, and the deep thrumming music of the new rulers of the world.

Why should they not rule it? We were only relics ourselves, we who had had the misfortune of surviving the plague. Out of every hundred thousand, only fifty or a hundred had survived. And as we scavenged in the ruins, as we bulldozed earth over the corpses we dragged from the areas where we meant to live, as we struggled to learn how to keep a generator or two running, a truck here and there, the radios we used only once a week, then once a month, then once a year, we gradually came to realize that there would be no more children. No one conceived. No one bore. The disease had sterilized us, almost all. There would be no recovery from this plague. Our extinction had not required a celestial missile to shatter the earth and darken the sky for a year; no other species shared our doom with us. We had been taken out surgically, precisely, thoroughly, a tumor removed with a delicate viral hand.

So we did not begrudge the elephants their possession of the fields and the forests. The males could knock down trees to show their strength; there was no owner to demand that animal control officers come and dispose of the rampaging beasts. The females could gather their children into barns and stables against the winter blast, and no owner would evict them; only the crumbling bones and strands of hairy flesh showed where horses and cattle had starved to death when their masters died too quickly to think of setting them free from their stalls and pens.

Why, though, had these males come into the city? There was nothing for them to eat. There was nothing for us to eat; when our bicycles gave out and we could cobble together no more makeshift carts, we would have to leave the city ourselves and live closer to the food that we gathered from untended fields. Why would the elephants bother with such a ruin? Curiosity, perhaps. Soon they would see that there was nothing here for them, and move on.

We found ourselves growing impatient as the hours passed, and the days, and still we kept encountering them on the city streets. Didn’t they understand that we lived in the heart of Poznan specifically because we wanted a human place? Didn’t they feel our resentment of their trespass? All the rest of Earth is yours; can you not leave undesecrated these crypts we built for ourselves in the days of our glory?

Gradually it dawned on us — dawned on me, actually, but the others realized I was right — that the elephants had come, not to explore Poznan, but to observe us. I would pedal my bicycle and glance down a cross street to see an elephant lumbering along on a parallel path; I would turn, and see him behind me, and feel that shuddering in my breastbone, in my forehead, that told me they were speaking to each other, and soon another elephant would be shadowing me, seeing where I went, watching what I did, following me home.

Why were they interested in us? Humans were no longer killing them for their ivory. The world was theirs. We were going to die — I, who was only seven years old when the plague came, am now past thirty, and many of the older survivors are already, if not at death’s door, then studying the travel brochures and making reservations, their Bibles open and their rosaries in hand. Were these males here as scientists, to watch the last of the humans, to study our deathways, to record the moment of our extinction so that the elephants would remember how we died with only a whimper, or less than that, a whisper, a sigh, a sidelong glance at God?

I had to know. For myself, for my own satisfaction. If I found the truth, whom else would I tell it to, and for what purpose? They would only die as I would die, taking memory with them into the fire, into the ash, into the dust. I couldn’t get any of the others to care about the questions that preyed upon me. What do the elephants want from us? Why do they follow us?

Leave it alone, Lukasz, they said to me. Isn’t it enough that they don’t bother us?

And I answered with the most perplexing question of all, to me at least. Why elephants? The other wild animals that roamed the open country were the ones one might expect to see: The packs of dogs gone wild, interbreeding back to mongrel wolfhood; the herds of cattle, breeding back to hardiness, and of horses, quick and free and uninterested in being tamed. The companions of man, the servants and slaves of man, now masterless, now free. Unshorn sheep. Unmilked goats. Sudden-leaping housecats. Scrawny wild chickens hiding from ever-vigilant hawks. Ill-tempered pigs rooting in the woods, the boars making short work of dogs that grew too bold. That was the wildlife of Europe. No other animals from Africa had made the journey north. Only the elephants, and not just from Africa — the elephants of India were roaming the orient, and on the most recent Radio Day we learned, through messages relayed many times, that they had somehow crossed the Bering Strait and were now, in ever greater numbers, grazing the prairies of America, small-eared cousins to the great-canopied beasts that now shadowed us on the streets of Poznan. I pictured them swimming, or piling onto boats that some last human pilot guided for them onto the stygian shore.
