By today’s date, the speakers of Proto-Indo-European are probably well-ensconced in their homeland, either Anatolia/the Caucasus/Northern Iran or (more likely according to the DNA evidence) the steppes north of the Black Sea. Nobody was writing the language down, but scholars have reconstructed a lot of it based on its daughter languages, which include English, Irish, Latin, Greek, Polish, Sanskrit, and Hittite, among many others. In 1868, August Schleicher wrote a little tale in reconstructed Proto-Indo-European. Here’s his version
Avis akvāsas ka
Avis, jasmin varnā na ā ast, dadarka akvams, tam, vāgham garum vaghantam, tam, bhāram magham, tam, manum āku bharantam. Avis akvabhjams ā vavakat: kard aghnutai mai vidanti manum akvams agantam. Akvāsas ā vavakant: krudhi avai, kard aghnutai vividvant-svas: manus patis varnām avisāms karnauti svabhjam gharmam vastram avibhjams ka varnā na asti. Tat kukruvants avis agram ā bhugat.
And the English translation
The Sheep and the Horses
A sheep that had no wool saw horses, one of them pulling a heavy wagon, one carrying a big load, and one carrying a man quickly. The sheep said to the horses: “My heart pains me, seeing a man driving horses.” The horses said: “Listen, sheep, our hearts pain us when we see this: a man, the master, makes the wool of the sheep into a warm garment for himself. And the sheep has no wool.” Having heard this, the sheep fled into the plain.
And here’s a sound file of the tale, based on more than a century’s linguistic work post-Schleicher, read aloud by linguist Andrew Bird
Here’s a transcription of this version
