6. Incipit of Zagrabiensis' Judicium...
The right hand image (No. 6) is the incipit of Martinus Zagrabiensis' Judicium de cometa que apparuit Anno Domini 1468. Zagrabiensis, who was also known as Martin de Ilkusch (1433-1493/94), was a good friend of Regiomontanus and a pupil of Martin Krol, the most famous Polish astronomer before Copernicus. He studied in Cracow, may have been in Vienna for some time, and was at Academia Istropolitana (University of Pozsony, now Bratislava) founded by King Mathias of Hungary in 1467.

Discussions of Zagrabiensis occur in a dissertation by Leslie Domonkos, Lynn Thorndike's History of Science and Experimental Magic, vol. 4, and T. Ortvay who wrote a definitive history of the University of Pozsony. We are indebted to Dr. Darin Hayton of Notre Dame University for discovering the details of Zagrabiensis' life. See also work on the comet of 1472.(Cont'd in the frame below)
