the works of many commonwealth authors are considered classics, including those of jan kochanowski ("pic. 10"), wacław potocki, ignacy krasicki, and julian ursyn niemcewicz. many "szlachta" members wrote memoirs and diaries. perhaps the most famous are the "memoirs of polish history" by albrycht stanisław radziwiłł (1595–1656) and the "memoirs" of jan chryzostom pasek ("ca." 1636–"ca." 1701). jakub sobieski (1590–1646) (father of john iii sobieski) wrote notable diaries. during the khotyn expedition in 1621 he wrote a diary called "commentariorum chotinensis belli libri tres" (diary of the chocim war), which was published in 1646 in gdańsk. it was used by wacław potocki as a basis for his epic poem, "transakcja wojny chocimskiej" ("the progress of the war of chocim"). he also authored instructions for the journey of his sons to kraków (1640) and france (1645), a good example of liberal education of the era.
