  "[Das] schaf und [die] rosse."[Ein] schaf, [auf] welchem wolle nicht war (ein geschorenes schaf) sah rosse, das [einen] schweren wagen fahrend, das [eine] große last, das [einen] menschen schnell tragend. [Das] schaf sprach [zu den] rossen: [Das] herz wird beengt [in] mir (es thut mir herzlich leid), sehend [den] menschen [die] rosse treibend. [Die] rosse sprachen: Höre schaf, [das] herz wird beengt [in den] gesehen-habenden (es thut uns herzlich leid, da wir wissen): [der] mensch, [der] herr macht [die] wolle [der] schafe [zu einem] warmen kleide [für] sich und [den] schafen ist nicht wolle (die schafe aber haben keine wolle mehr, sie werden geschoren; es geht ihnen noch schlechter als den rossen). Dies gehört-habend bog (entwich) [das] schaf [auf das] feld (es machte sich aus dem staube).

  "The Sheep and the Horses"[On a hill,] 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.

  以上這些文段之間的一些區別僅僅在於更換不同的拼寫方式:例如 "w" 和 "u̯", 只是在用不同的方法表示相同的子音型 "u "語音;然而,其餘的許多區別則是因為不同學者對於原始印歐語的音位學和詞法學系統的觀點存在分歧。  施萊謝爾的重構版本中認為 "o/e" 語音是二次產生的,他的原始印歐語版本相較於當今的重構版本更加傾向基於梵語。  希爾特引入了 "o/e "語音,音節子音,圓脣軟顎音和軟顎音。  萊曼和茲古斯塔引入了一些替代性的詞位(關係代詞"kwesjo";單詞 "nēr" "男人"),並開始向喉音理論的方向行進。他們的文字的一個特點是含有 "h" ("wl̥hnā"),他們認為它是原始印歐語中僅有的單獨喉音。  亞當斯是第一位在其寓言版本中完全反映喉音理論的學者。從文字上來看,他似乎假設存在四個不同的喉音音位,因此亞當斯的文字中也未再出現長音 "ā "。  科特蘭的版本從很多方面來看都和之前的文字有著根本的差異——第一,他繼承了聲門音理論,在字母后加撇號來表記聲門塞音("t' ")並省略了送氣濁塞音; 第二,他分別使用最可能的音值取代了每一個令人難以理解喉音符號: "h" = "ʔ" (聲門塞音),"h" = "ʕ" (濁咽擦音),"h" = "ʕw" (圓脣化的濁咽擦音)。此外,科特蘭對於許多名詞與動詞形式中的母音交替和變換現象亦持有與其他學者不同的意見。

  在雷利·史考特的電影《普羅米修斯》中,原始印歐語被用於人類宇航員和一個外星人“工程師”之間的一段短對話; 在這之前的一個場景中,機器人“大衛”(邁克爾·法斯賓達飾)在準備第一次與“工程師”交涉時,對著互動式計算機練習背誦施萊謝爾的寓言。
施萊謝爾寓言 (英語:Schleicher's fable,原始印歐語:"H2óuis h1éḱuōs-kwe") 是由一段使用重構的原始印歐語 (Proto-Indo-European,PIE) 編寫的一段文字,於1868年由語言學家奧古斯特·施萊謝爾發表;施萊謝爾是第一位使用原始印歐語撰寫文字的學者,該寓言的題目是《"Avis akvāsas ka" ("羊[Ewe]與馬[Eoh]")》。此後隨著時間的推移,由於人們對原始印歐語樣貌的看法在不斷變化,許多其他學者又陸續釋出了施萊謝爾寓言的修訂版本;出過去150年間,眾多學者們的不斷努力使重構的原始印歐語發生了顯著的變化,從這篇寓言亦可見一斑。
