Mentioned, and first among them Rzaczynski, who in 1721 brought out at Sandomirsk the Historia naturalis curiosa regni Poloniae, to which an Auctuarium was posthumously published at Danzig in 1742.
C. 1115), that 3' who generally styled himself duke of Poland, or dux totius Poloniae, claimed a sort of supremacy among these little states, a claim materially strengthened by the wealth and growing importance of his capital, Cracow, especially after Little Poland had annexed the central principality of Sieradia (Sieradz).
Scholars desiring to explore for themselves the sources of Polish history from the nth century to the 18th have immense fields of research lying open before them in the Acta historica res gestas Poloniae illustrantia (1878, &c.), the Scriptores rerum polonicarum (1872, &c.), and the Historical Dissertations (Pol., 1874, &c.), all three collections published, under the most careful editorship, by the University of Cracow.
For more complete bibliography see Jozef Korzeniowski's Catalogus actorum et documentarum res gestas Poloniae illusirantium (Cracow, 1889), and Ludwik Finkel's Bibliography of Polish History (Pol., Lemberg, 1891).
Five years later appeared the Annales Poloniae of Sarnicki.
About the close of this period we have some valuable writers on Polish history, which now began to be studied critically, such as Hartknoch in his Altand Neues Preussen (1684), a work in which are preserved interesting specimens of the old Prussian language, and Lengnich (1689-1774), author of the valuable Jus publicum regni Poloniae, which appeared in 1742.
The works of Lelewel have separate mention (see Lelewel); but here may be specified the labours of Narbutt, Dzieje starozytne arodu litewskiego (" Early History of the Lithuanian People"), published at Vilna in nine volumes, and the valuable Monumenta Poloniae historica, edited at Lemberg by Bielowski, of which several volumes have appeared, containing reprints of most of the early chroniclers.
Here appeared the Monumenta Poloniae historica of Bielowski, previously mentioned; but Polish in this province has to struggle with the Red-Russian or Ruthenian, a language or dialect which for all practical purposes is the same as the Southern or Little Russian.
