Martynas Mažvydas’ Catechism (Königsberg, 1547), the first book written in Lithuanian, marked many first times: the first original work of Lithuanian poetic literature, the first hymns with musical notations in the Lithuanian language, and the first Lithuanian textbook.

Hymn
In Catechism, we also find the first Lithuanian encrypted text—an acrostic—which identifies Martynas Mažvydas as the book’s author. The acrostic was discovered in 1938 by Polish researcher Jan Safarewicz, but it was fully deciphered only in 2019 by Baltic scholar Ilja Lemeškinas. The scholar determined that the first lines of the Lithuanian preface in verse are also significant, and the entire acrostic reads as follows: “B[accalaureus] J[uris] MARTJNVS MASVJDJVS” (Martynas Mažvydas, Bachelor of Laws).
And at the end of Catechism, just before the hymnal section (p. C4), Lemeškinas discovers yet another acrostic—
a continuation of the preface’s acrostic in the four-line invocation “Skaititaiap”: “BJ TP” (Baccalaureus Juris Titulum Posuit, Eng. Bachelor of Laws placed the sign of the cross).
Only two known surviving copies of the first Lithuanian book currently exist in the world, and they are held in the libraries of Vilnius University and the University of Toruń (Poland). It is believed that approximately 200 copies were printed.

The copy held by Vilnius University Library was received from Maxim Gorky Scientific Library in Odessa (Ukraine) in 1957, in exchange for Abraham Ortelius’ atlas Theatrum Orbis Terrarum*, published in Antwerp in 1570, and the Third Statute of Lithuania**, printed in Vilnius in 1588.
