Origin of the work:
1978 Prague, J. A. Comenii Opera omnia, vol. 3.
The third part of the Sorrowing is the despairing monologue of the Suffering Person after the Peace of Westphalia in 1648, which closed the road to their homeland to the Czech evangelicals. The reproaching of God gives way to pleas and humble hope. This third part was discovered only in the 1890s by Ján Kvačala, and was definitively identified by Jan Blahoslav Čapek in 1957.
