Old Prussian: what the surviving records can tell us

A Baltic language, not an early form of German

Old Prussian is the conventional name for a Baltic language documented in the southeastern Baltic region. Dini treats it separately from Lithuanian and Latvian and from German as used in later Prussia. A historical territory’s name should not be taken as proof that everyone who lived there spoke the same language.^[1]

Its surviving evidence is much smaller and less varied than the documentation available for Lithuanian and Latvian. That uneven record limits what can be established about pronunciation, grammar, regional variation and everyday conversation.^[1]

What survives

The main categories are word lists, short manuscript passages and three Lutheran catechisms. Dini’s survey includes the Elbing Vocabulary, the vocabulary associated with Simon Grunau, the Trace of Basel, and scattered words, names and glosses. He also discusses the Trace of Crete, whose identification as Old Prussian or Old Lithuanian remains disputed in his account. These records do not all have the same date, provenance or evidential value.^[1]

The first two catechisms were printed in 1545; the third followed in 1561. The third, usually called the Enchiridion, preserves substantially more continuous text than the first two. It is therefore central to grammatical research, although its purpose was religious instruction rather than a neutral survey of spoken usage.^[1]

A word list can preserve a vocabulary item without showing how it behaved in a sentence. A translated catechism can provide sentences while also reflecting the source language and the translator’s choices. The kind of document therefore determines the questions it can answer.^[1]

The Basel fragment: an example of unresolved interpretation

The Trace of Basel consists of two short lines inserted into a manuscript. Ardoino locates it in Basel University Library’s manuscript F.V.2, folio 63r. It appears near a colophon bearing a 1369 date, but whether that date also applies to the short Baltic text is a separate question.^[2]

The writers disagree about the person who recorded it. Ardoino argues for examining the layout, handwriting and additions on the page, and allows for a Baltic variety close to Old Prussian. Kortlandt’s 2018 response instead defends the possibility of a Bavarian scribe taking down a Prussian speaker’s words. These are competing explanations, not established biographies.^[2][3]

For a general reference, the appropriate conclusion is limited: a short text can be important without every proposed date, place and speaker having been identified securely. The manuscript’s physical context belongs alongside the linguistic argument, rather than disappearing behind a confidently retold anecdote.

The catechisms need textual criticism too

The 1561 translation is associated with the pastor Abel Will and the Prussian informant Paul Megott. Dini also records a different hypothesis about how the work was organised, involving oral translation and scribes. The text should not be treated as an unmediated recording by a single known native author.^[1]

The spelling does not give an entirely transparent guide to pronunciation. Dini discusses editorial corrections, competing readings and possible German interference. When a modern edition supplies a restored form, that restoration must be distinguished from the letters visible in the historical document.^[1]

Dini’s 2024 study adds another distinction: a work, a surviving printed copy and a later handwritten copy are different objects. His catalogue discusses two complete printed copies, an incomplete printed copy and a later handwritten copy labelled VH. Calling these simply four surviving original printed books would erase that difference.^[4]

That study follows the movement and preservation of these witnesses, including their wartime histories. Textual research consequently involves libraries and archives as well as grammar: a reading can depend on which copy or reproduction an editor was able to consult.^[4]

Language loss and later revival are different histories

Dini’s account describes declining evidence for spoken Old Prussian in the seventeenth century and uncertainty in later reports. One often-repeated note refers to an elderly speaker’s death in 1677 while itself allowing that others might remain. It cannot establish a securely known final speaker or a precise day when the language ceased to be used.^[1]

The same book discusses twentieth-century attempts to develop New Prussian using the surviving evidence and linguistic reconstruction. Those projects are part of the history of revival. A form created for a modern revival is not, by that fact alone, evidence that the same expression was used in a medieval village.^[1]

When consulting an edition or a revival resource, ask whether an item is directly attested, an editor’s reading of damaged or ambiguous writing, or a new reconstruction. Keep the edition and page reference with it. That distinction makes the surviving evidence more useful without pretending that it answers every question about historical Prussian communities.
