Map of the two Americas from Cosmography of Ptolemy by Jan of Stobnica, 1512
Jan of Stobnica was one of Kraków's adherents of Scotism, a philosophical school brought in from Paris first by Michał Twaróg of Bystrzyków (ca. 1450 - 1520). Jan of Stobnica became Michał's most prominent student. Jan's most famous work, entitled "Introductio in Ptholomei Cosmographiam" (Introduction to the Cosmography of Ptolemy) featured some of the first maps printed in Poland. Likewise, his edition of Ptolemy first contained a map of North and South America showing the connection of the two continents by an isthmus. It is one of the oldest known references to North America with the Gulf of Mexico delimited by the peninsula of Florida, peculiarly labeled "Isa-bella" (see engraving), which corresponds to the name of Cuba in primitive times, which in fact he left it blank."Cosmographiam" by Jan of Stobnica, from 1512, are among some of the most precious Polonica of the New York Public Library holdings.
