The first complete Bible in Finnish. Before it there was Mikael Agricola's New Testament of 1548 and pieces of the Old; after it there was a whole Bible in a language that had barely been written down. Four scholars did the work between 1638 and 1641 — Eskil Petraeus, Martinus Stodius, Henricus Hoffman and Gregorius Matthaei — under Isaacus Rothovius, Bishop of Turku, who pushed the project through. Finland was part of Sweden, and the volume appeared in 1642 under the patronage of Queen Christina.
They translated from the Hebrew and the Greek with Luther's German beside them. The Swedish Bible of Gustav Vasa was the other book on the table; it is not in this corpus, so the chain here records only the Luther. The 1642 Biblia's larger effect was on Finnish itself. A language with almost no written prose acquired, in one volume, a vocabulary and a cadence for everything from law to lament — and every later Finnish Bible is a revision or a successor of it rather than a fresh start.
In this reader it is where the Finnish line stops being Finnish. Three rungs below Kirkkoraamattu 1933/38, beneath Biblia 1776, this edition appears; and beneath it Luther's German of 1545. That is the only place in the corpus where one vernacular Bible's chain descends into another vernacular instead of dropping straight to the Hebrew and the Greek. The text here comes from the Kotus VKS corpus of Old Literary Finnish, which is why the spelling you see — “tulcon walkeus” — is the 1642 printing's own and not modernised.
