Career
He is also an inventor of modern Upper Sorbian poetic language. He has been described as "the classical writer of Sorbian literature."
As a Sorbian writer, he felt that writing the Serbian language and using it for literature and for education would be important for preserving the vitality and distinctiveness of Sorbian culture. But he also realized that it was a double-edged sword, in that education would reduce the isolation of Sorbian culture, making it more vulnerable to outside (mostly German) influence.
