Struminski's study concentrates on text-critical, biographical, and linguistic aspects of the Speech in order to demonstrate that the original (no longer extant) was in Ukrainian and that it was an actual speech delivered at the Warsaw Diet, not a parody of such a speech as has been assumed. The author has discovered hitherto unknown copies of the text and archival materials concerning the historical Meleško. With the use of this data Struminski was able to build a stemma for the interrelationship of the extant copies and to reconstruct the archetype of the text.

Further, the author has established little known facts of Meleško's life and connected them with the origin of the Speech. The study concludes with a full glossary to the text, with translation of all foreign words into English.

The work will be useful to experts and students in the field of Slavic languages and literature.
