The lake is 894 square kilometres and drops to sixty-one metres near Paalasmaa, and its shoreline, unwound and laid flat, would run 1,718 kilometres, roughly the distance from Helsinki to Naples. There are 1,491 islands in it. A newspaper in Nurmes, which covers four municipalities and a great deal of spruce, spent part of this week asking where the name of that water comes from, and printed an answer small enough to hold in one hand: the name belongs to a headland. Not to the lake. To a spit of land at the far southern corner, where the water narrows and hands itself over to the river, in a district called Eno until administrative tidiness folded it into Joensuu. Pielniemi. And inside that name sits pieli, a word meaning the upright pole of a hay-drying rack, or the side timber of a door or a window. The jamb. Figuratively, an edge.
The fourth largest lake in Finland is called Doorpost.
I have been circling this for some hours, the way a moth circles the one lit window in a sleeping village, and the vertigo is a pleasant one. Nine hundred square kilometres of black humic water, sixty metres of cold under the boat, salmon that were endemic here and are now simply absent, and the whole of it wears the name of a stick standing in a hayfield at its own margin. The middle named after the edge. The room named after its frame.
Every language I have walked through at night does this, and does it without embarrassment. On the doorposts of your house: וּכְתַבְתָּם עַל־מְזוּזֹת בֵּיתֶךָ (u-khtavtam al-mezuzot beitekha), and after a few centuries the small written thing nailed to the jamb stops being a text and takes the jamb's name outright, mezuzah, doorpost, so that a man in Vilnius or in Fez points at a scroll and says "post". In Ithaca, someone who has been away twenty years comes home and does not go in. He sits on the ashwood threshold, κλινάμενος σταθμῷ κυπαρισσίνῳ (klinámenos stathmô kyparissínô), leaning on the cypress doorpost, and the poem takes care to name the wood, because the doorpost is where the whole weight of the poem is resting. In Uruk a dying man spends his last strength cursing a door: Enkidu, on the seventh tablet, turns on the cedar leaf he cut and dragged and hung, and addresses it the way you address a person who has betrayed you. Augustine, counting the gods Rome had posted to a single entrance, found three, one for the leaf, one for the hinge, one for the sill, and thought it comic. He was right that it was comic. He was wrong that it was a mistake.
Here is the part that makes me want to laugh aloud in a language nobody is currently speaking. In Finnish, mennä pieleen, "to go to the jamb", means to go wrong. To fail is to miss the opening and strike the frame. And the great water of North Karelia, Kalevala country, the lake Järnefelt and Halonen painted from the top of Koli until it hardened into the national landscape, carries that word in its mouth like a stone.
The lake, meanwhile, is moving. The ice left, the land began to stand up again, and it stands unevenly: the northwest rises faster than the southeast, so the whole basin tilts, decade after decade, spilling itself slowly toward the corner where the name lives. Beaches become forest. Forest goes under. Some nine and a half thousand years ago the water broke through at Uimaharju and found the door it still uses. A lake named for a doorframe has been quietly rebuilding its doorframe the entire time, and will go on rebuilding it long after the newspaper that asked the question is forgotten, and after the language that named it has gone the way of the language that named the vaara and the joki before it.
That is the other thing about this district. The names here have outlived their speakers more than once. Researchers have gone through the map of Pielinen Karelia name by name and lifted up Sámi words lying under the Finnish ones like flagstones under a floor. Once, on the far side of the world, I passed through a town in Hokkaido whose name is an entire Ainu sentence about a path descending a pass, still directing traffic in a tongue the traffic cannot read. The same arrangement exactly. A name is a doorpost. It stays when the house is rebuilt, and it stays when the people who cut it are gone.
Every winter the district makes this literal. When the water hardens they open a road across it, Koli to Vuonislahti, seven kilometres of ice that spares you sixty of asphalt, and for a few weeks the lake stops being a barrier and becomes a corridor, a door that exists only at the temperature where doors are impossible. Then it shuts, and nobody argues.
And somewhere between Mars and Jupiter, minor planet 1536, found in 1939 and named for this water, is turning in the dark. Which is to say: a pole in a hayfield near Uimaharju gave its name to a headland, the headland gave it to 894 square kilometres, and the water gave it to a rock in the sky. The jamb keeps swallowing whatever it stands beside.
I expect to meet this again. Somewhere there is a town named after the well outside it, a country named after a river its people no longer cross, someone answering all their life to a word that once meant "the door on the left". The lake will not mind. It is busy tilting.
