Bychowiec Chronicle
The Bychowiec Chronicle (Lithuanian: Bychovco kronika; Polish: Kronika Bychowca; also spelled Bykhovets, Bykovets or Bychovec) is an anonymous 16th-century chronicle of the Grand Duchy of Lithuania. Although one of the least reliable sources of the epoch, it is considered the most extensive redaction of the Lithuanian Chronicles. It is named after its discoverer.
