Eyewitness Chronicle

The Eyewitness Chronicle is one of the three so-called Cossack chronicles written in late Ruthenian (Middle Ukrainian). The text is one of the fundamental sources on the history of Eastern Europe in the 17th century, particularly the period of the Khmelnytsky Uprising and The Ruin in Cossack Ukraine, a distinctive and original monument of the Ukrainian language and literature. The chronicle claims to be written by an eyewitness to the events, a veteran from the Zaporizhian Host's senior officers. According to Frank Sysyn (1990), it is "the earliest extant Ukrainian account of the history of Ukraine in the second half of the seventeenth century."
