A history of translation: from the Rosetta Stone to AI

The word translate derives from the Latin translatum, to carry across. For at least 4,000 years, human beings have been carrying meaning across the barriers of language: copying the Epic of Gilgamesh from Akkadian into other tongues around 2000 BC, decoding the Rosetta Stone's three scripts, debating whether to render Scripture word-for-word or sense-for-sense, and now building neural networks that translate 100 billion words a day. Every era of human history has left its mark on translation, and translation has left its mark on every era of human history.

Translation has supported everything from the spread of world religions to the advance of science, from the development of national languages to the survival and growth of international business. That role has not diminished. It has only accelerated.

Why the history of translation matters

Translation has contributed to everything from the large-scale spreading of religions to the development of modern languages. It has enabled communications, insights, and understandings that would not otherwise have occurred. It has also been shaped by power: throughout most of history, translation was the purview of the educated elite (royalty, scholars, religious institutions) which means the surviving record reflects their priorities and perspectives.

One byproduct of this is that almost all surviving ancient translations were produced by men, leaving few insights from a female perspective. This imbalance has persisted into the modern era: far more books written by male authors are translated into English than books written by female authors. Campaigners and organizations are working to address this — including Professor Emily Wilson's 2017 translation of the Odyssey, the first by a woman in the text's 3,000-year history.

Ancient translation: The first 2,500 years

The earliest known translations

The origins of translation as a documented practice are older than most people realize. Around 2500 BC, symbols were translated from Sumerian to Eblaite on clay tablets — some of the earliest physical evidence of systematic translation. Around 2000 BC, the Sumerian Epic of Gilgamesh was translated from Akkadian into various Asian languages, making it among the first known works of literary translation.

The Septuagint

In the Western world, one of the most consequential early translation projects was the Septuagint: a collection of texts from the Hebrew Bible and deuterocanonical books translated into early Koine Greek between the 3rd and 1st centuries BC. The name derives from the tradition that 70 translators worked on it simultaneously — producing, according to legend, identical translations. The Septuagint enabled Jews in the diaspora, whose Hebrew language skills had eroded through geographical dispersal, to read the Scriptures in Greek. It became the version of the Old Testament most familiar to the earliest Christians, and its influence on Christian theology and Biblical language has been incalculable.

The Rosetta Stone

Perhaps the most famous artifact in the history of translation is the Rosetta Stone. Dating to 196 BC and discovered in 1799 during Napoleon's Egyptian campaign, the stone carries a decree issued by Ptolemy V Epiphanes inscribed in three scripts: Ancient Egyptian hieroglyphs at the top, Demotic script in the middle, and Ancient Greek at the bottom. The presence of the same text in three scripts provided the key that allowed 19th-century scholars (most notably Jean-François Champollion in 1822) to decipher Egyptian hieroglyphics after nearly fourteen centuries of silence.

The Rosetta Stone arrived at the British Museum in 1802 and is consistently cited as the museum's most visited object, drawing millions of visitors annually. It has also become a focal point of the ongoing debate about the repatriation of cultural artifacts: Egypt has called repeatedly for the stone's return, most recently with renewed urgency as the 200th anniversary of hieroglyphic decipherment was marked in 2022. The stone's presence in London remains contested, which gives an artifact of translation its own unresolved translation problem.

The classical and medieval era

Religious translations

Since the earliest days of the craft, religious texts have been a primary driver of translation. Saint Jerome (the patron saint of translation) was a Christian priest who, between 383 and 404 AD, produced the Vulgate: a Latin translation of the Bible that became the standard text of the Catholic Church for over a millennium. Jerome's approach was significant not just textually but methodologically: he is credited with coining the principle of translating sense for sense rather than word for word, a debate that continues in translation theory to this day.

Buddhism and East Asia

Translation also drove the spread of Buddhism across Asia during the first millennium AD. The Buddhist monk Kumārajīva (344–413 AD) translated a wide range of religious texts from Sanskrit into Chinese during the 4th century, including the Diamond Sutra — celebrated for the clarity with which it renders the meaning of the originals. The Tangut Empire later intensified this work, using block printing technology as part of the translation and distribution process.

King Alfred and the English language

In England, King Alfred the Great is credited with doing much to grow the English language through his commitment to translating key Latin works (including Boethius's The Consolation of Philosophy and Bede's Ecclesiastical History) into Old English. Alfred's translations were deliberately targeted at a non-scholarly audience, reflecting an early version of the debate about who translation is for.

The Toledo School of Translators

The Arabic dominance of the medieval scholarly world produced a remarkable translation moment in Spain. After the Reconquista, King Alfonso X of Castile (drawing on a tradition that had developed under earlier rulers) transformed Toledo's Schola Traductorum into a systematic multilingual translation enterprise in the 13th century. Scholars of different faiths (Christian, Muslim, and Jewish) collaborated on translations of Arabic, Latin, and Hebrew scientific, philosophical, and medical texts. This work was central to transmitting the Greek intellectual tradition to Renaissance Europe through Arabic intermediaries: the translation of Aristotle and other Greek thinkers into Arabic, and then from Arabic into Latin, was the route by which much of ancient learning re-entered Western Europe.

Geoffrey Chaucer

In literary translation, Geoffrey Chaucer stands out as a transformative figure. His translations, adaptations, and original works during the late 14th century drove Middle English forward as a literary language during an era when French and Latin still dominated English intellectual and official life. Chaucer translated Le Roman de la Rose from French and Boethius from Latin, alongside composing original works — demonstrating how translation and literary creation have always been deeply intertwined.

The Reformation and the printing press

Gutenberg and the democratization of text

Johannes Gutenberg's invention of movable-type printing around 1450 transformed translation from a scribal and courtly enterprise into a mass-cultural one. The first book Gutenberg printed was the Bible in Latin. The printing press made it possible to distribute texts in thousands of copies rather than dozens of hand-copied manuscripts — which meant that translations, once completed, could reach literate readers across entire nations.

William Tyndale and the English Bible

The intersection of the printing press and religious translation produced one of history's most consequential (and most dangerous) translators: William Tyndale. In 1526, Tyndale published the first printed New Testament in English, translated directly from the Greek rather than from the Latin Vulgate. The Church of England's hierarchy opposed his work, and Tyndale had to complete most of his translation in exile in Continental Europe.

Tyndale was arrested in Antwerp in 1535, convicted of heresy, and executed in 1536 — strangled and burned at the stake. His dying prayer was reported as "Lord, open the King of England's eyes!" Within a few years, King Henry VIII ordered English Bibles placed in every parish church. The King James Bible of 1611 (arguably the most influential single translation in the English language) is approximately 84% word-for-word Tyndale's translation, revised and updated. Tyndale has no grave, but his monument is in the language of every English Bible still in use.

Martin Luther and the vernacular principle

Martin Luther's translation of the Bible into German (1522–1534) established a parallel principle in the German-speaking world. Luther argued that a translator must write into their own native language — using the speech of ordinary people, not the Latin of scholars. This insistence on vernacular translation drove the standardization of High German as a written language and gave Protestant communities across Europe direct access to the Scriptures in their own tongues.

Translation theory: Sense for sense vs. Word for word

The great theoretical debate in translation (how literal should a translation be?) has been present in the craft from its earliest recorded moments.

Saint Jerome established the sense for sense principle: a translator should render the meaning of a text, not its literal words. His Latin Vulgate is the product of this philosophy.

Martin Luther added a democratic dimension: translation should use the language of ordinary people, not scholars. A translator should listen to how people actually speak, not how grammarians say they should.

Marsilio Ficino's translation of Plato and Erasmus's translation of the New Testament in the 15th and 16th centuries began moving in a different direction: where so many religious and philosophical beliefs were tied to the precise words of Scripture, accuracy to the source text became paramount.

Eugene Nida, the 20th-century translation theorist who oversaw Bible translation for the American Bible Society, formalized this debate as formal equivalence (word-for-word) versus dynamic equivalence (thought-for-thought). His distinction shapes not only contemporary Bible translation (where some versions prioritize the original text structure while others prioritize modern comprehension) but virtually all thinking about literary and technical translation. The question every translator still faces, in every project, is a version of Nida's question: what is the most important thing to preserve?

The modern era and machine translation

The first machine translation experiments

The history of machine translation begins not with software but with wartime intelligence. Warren Weaver's influential 1949 memorandum proposed using computers to solve translation as a code-breaking problem — the same mathematical logic that cracked the Enigma cipher might, he argued, decode the structure of language. The Georgetown-IBM experiment of 1954 translated 60 Russian sentences into English automatically, generating significant optimism about the future of automated translation.

That optimism was sharply corrected by the 1966 ALPAC report, which concluded that machine translation was twice as expensive and twice as slow as human translation, and that fully automatic high-quality translation was not achievable in the near future. Funding dried up, and the first era of machine translation research largely ended.

Statistical and neural machine translation

Machine translation returned in the 1990s with statistical methods, using large bilingual corpora to learn translation patterns statistically rather than through handcrafted rules. By 2006, Google Translate had launched, initially using statistical machine translation.

The defining shift came in 2016, when Google Translate switched entirely to neural machine translation (NMT) — deep learning systems that process entire sentences as context rather than translating word by word. The quality improvement was significant and immediate. DeepL launched in 2017, using specialized neural architecture to produce translations widely rated higher quality than Google Translate's for European language pairs. The 2017 Transformer architecture from Google Brain (which replaced recurrent neural networks) established the technical foundation that underpins all modern machine translation systems.

AI and the contemporary translation landscape

The arrival of large language models (GPT-4, Claude, Gemini, and others) from 2022 onward introduced a further dimension. Unlike dedicated translation engines, LLMs can explain their translation choices, handle unusual registers and contexts, and process documents with long-range dependencies that traditional MT engines struggle with. Google Translate's Gemini-powered upgrade in 2025 added live speech translation in 70+ languages and language practice functionality, with real-time conversational capability. DeepL's 2025 updates expanded its Voice API and launched DeepL Agent, an autonomous AI coworker for translation workflow automation.

54% of language service providers had integrated AI or LLMs into their business workflows by 2025, up from a third in 2024. The pace of adoption is accelerating.

What has not changed is the requirement for human expertise in high-stakes contexts. Medical, legal, and regulatory translation continue to require certified human translators. Literary translation requires cultural sensitivity and creative judgment that no current AI system consistently delivers. As the history of the craft demonstrates, translation has always adapted to available technology (from clay tablets to printing presses to neural networks) while maintaining the core requirement: that meaning carries accurately from source to target.

Tomedes' model reflects exactly this: certified human translators working with AI-enhanced tools, across 270+ languages, with ISO 17100:2015 and ISO 18587:2017 certification covering both translation quality and machine translation post-editing. The Tomedes translation services page covers the full scope.

Notable translators throughout history

Translation history is shaped not just by events but by individuals. A few who warrant mention:

Saint Jerome (347–420 AD) — producer of the Latin Vulgate; patron saint of translation; coined the "sense for sense" principle.

Kumārajīva (344–413 AD) — Buddhist monk whose Sanskrit-to-Chinese translations spread the Dharma across East Asia with a clarity unmatched by earlier translators.

William Tyndale (c.1494–1536) — executed for translating the New Testament into English; his work forms the linguistic foundation of the King James Bible.

Martin Luther (1483–1546) — his German Bible established the vernacular translation principle and helped standardize written High German.

Constance Garnett (1861–1946) — English translator who introduced Tolstoy, Dostoevsky, and Chekhov to the English-speaking world.

Gregory Rabassa (1922–2016) — translator of Gabriel García Márquez and other Latin American writers; García Márquez reportedly preferred Rabassa's English One Hundred Years of Solitude to his own Spanish original.

Lydia Davis (1947–present) — translator of Proust and Flaubert, and a significant literary figure in her own right.

Emily Wilson (1971–present) — the first woman to translate Homer's Odyssey into English, published in 2017; her translation brought fresh attention to the gender dynamics of translation history.

Frequently asked questions

Q: When was the first translation made?
A: The earliest documented translations are from around 2500 BC, when Sumerian symbols were translated into Eblaite on clay tablets. Around 2000 BC, the Epic of Gilgamesh was translated from Akkadian into other Asian languages. The practice of systematic translation is therefore at least 4,500 years old.

Q: What is the most significant translation in history?
A: Significance depends on the metric. By religious impact: the Septuagint (Hebrew Bible into Greek, 3rd–1st centuries BC) and Saint Jerome's Latin Vulgate (382–404 AD) shaped Christianity's development across the Western world. By linguistic impact: William Tyndale's English New Testament (1526) and the King James Bible (1611) transformed the English language. By scientific impact: the Toledo translations of Arabic and Greek texts into Latin from the 12th to 13th centuries were decisive in transmitting ancient knowledge to Renaissance Europe.

Q: Who invented machine translation?
A: The theoretical foundations were laid by Warren Weaver's 1949 memorandum proposing that translation could be approached as a code-breaking problem. The Georgetown-IBM experiment of 1954 produced the first publicly demonstrated machine translation system, translating 60 Russian sentences into English. Modern neural machine translation emerged in 2015–2016 with Google's switch to neural MT and the subsequent launch of DeepL in 2017.

Q: What is the difference between formal and dynamic equivalence in translation?
A: Formal equivalence (word-for-word) prioritizes structural and lexical fidelity to the source text, translating as literally as possible. Dynamic equivalence (thought-for-thought), a concept developed by Eugene Nida in the 1960s, prioritizes conveying the meaning and effect of the source text in natural target-language expression, even if this requires departing from the source structure. Most professional translation involves judgments along this spectrum, with the appropriate approach depending on the text type, audience, and purpose.

Q: Why is William Tyndale important to translation history?
A: Tyndale produced the first printed New Testament in English (1526), translated directly from the original Greek rather than the Latin Vulgate. He completed much of his work in exile and was ultimately executed for heresy in 1536. The King James Bible of 1611 — arguably the most influential translation in the English language — is approximately 84% Tyndale's words, revised and updated. His execution for the act of translation makes him one of the most dramatic examples of translation as a politically dangerous act.
