Poniżej fragment opublikowanego wykładu:

The period of Cossack revolts, and the period of wars of deliverance against the Swedes, is followed by a third period of prolonged struggles with Turkey, fitly celebrated in Sienkiewicz’s third great  novel on the epoch, Pan Michael.

The Cossacks once more unite against Poland with Turks and Tartars. Sobieski defeats them at the head of an army put into the field a t his own expense (1667). The danger increases when the election of a weak king, Michael Wiśniowiecki, proves a disastrous failure. Poland lapses into disgraceful weakness: the Brandenburg Elektor – once a vassal – now insults Poland with impunity by high-handed action, and the Turks invade the South-East  in formidable powers: for the first time in Polish history they are actually bought off by a shameful tribute. Another great victory of Sobieski’s over the Turks on the old battlefield of Chocim (1673) makes him the most popular man in Poland, and finally carries him to the throne, which he occupies from 1674 to 1696.( A course of lectures delivered at king’s college, University of London by Roman Dyboski, P h .D)… – cały artykuł Bożeny Ratter
