This first half of the sixteenth century witnessed the
continued ascendancy of Latin as the literary language
and the growing discredit and degradation of the
vernacular ; this in spite of the fact that Polish was
making headway amongst the upper classes in the
newly-acquired territories to the East, whither families
migrated in numbers from Poland proper and where
by their urbanity and sociability they converted to their
language, if not to their faith, those Lithuanian and
Russian nobles who had till then been faithful to the
social           of Muscovy.
