Claim: Fürstlich Sächsischer Hofbuchdruckerei zu Altenburg moved to Altenburg in Thuringia in 1604; its earliest work was published in 1606.
Evidence: In 1604, after the duke's death, the press moved to Altenburg. Fürstlich Sächsischer Hofbuchdruckerei of Altenburg, Germany, is used generically in this article to denote a succession of book printers (sometimes synonymous with "publishers") based in Altenburg, in the German state of Thuringia (formerly East Germany), that — under various capacities, names, and owners – have endured as one continuous printing operation, without interruption (save and except wars), for four hundred and twenty-six years — since 1594, the early modern German period. The earliest extant published work from the Altenburg press is Lotio Pedum (1606).
