By the side of the name of Czartoryski, shines that of Potocki. More than one member of this illustrious family had in former times acquired the right of citizens in the republic of letters. Count Paul Potocki and his grandson Anthony, in the seventeenth and beginning of the eighteenth century, were both equally celebrated for their talents. The works of the former were published by count Zaluski, under the title of _Genealogia Potockiana_; the speeches and addresses of the latter are partly printed in Daneykowicz' _Suada Polona_, and were in their time considered as models. But the most elevated rank in this family is occupied by the two brothers Ignatius and Stanislaus Kostka Potocki, whether as patriots and statesmen, or as writers and patrons of science. Ignatius, besides promoting several literary undertakings, and bearing the expenses of more than one journey for the purposes of science and learning, was himself a distinguished writer. He translated Condillac's work on logic, and introduced it into the Polish schools as a class book. His merits in respect to public education were great; he was one of the most urgent promoters of the emancipation of the serfs; and at his death in the year 1809, he left behind the reputation of a true friend of the people. His brother Stanislaus Kostka, although entertaining the same political principles, did not take the same active part during the struggles of the Poles for their expiring independence; he retired to Austria after the king had joined the confederation of Targowicz, and there devoted himself entirely to his studies. In 1807 he returned to his country; and there, as president of the department for schools and education, he found means to carry out his enlightened views and benevolent intentions for the good of his country. At the foundation of the kingdom of Poland in 1815, he was made minister of public instruction, and was always found at the head of every noble and patriotic undertaking. From his oratorical powers, he was called _princeps eloquentiæ_. In respect to genius he was above his brother; although the latter seems to have surpassed him in energy of character. His principal work, "on Style and Eloquence," was published in 1815; another work of value is his translation of Winkelmann's book on ancient art, which he accompanied by illustrations and remarks, but did not finish. His influence on Polish literature was decided.[51] Another nobleman, distinguished as an orator and political writer, was Hugo Kollantay, count Sztumberg, who published, together with Ignatius Potocki, a history of the constitution.
