A Literary Polish language breakthrough came under the influence of the Reformation with the writings of Mikołaj Rej. In his "Brief Discourse", a satire published in 1543, he defends a serf from a priest and a noble, but in his later works he often celebrates the joys of the peaceful but privileged life of a country gentleman. Rej, whose legacy is his unbashful promotion of the Polish language, left a great variety of literary pieces.Łukasz Górnicki, an author and translator, perfected the Polish prose of the period. His contemporary and friend Jan Kochanowski became one of the greatest Polish poets of all time.
