Polish "glosses" may have been written by Copernicus

Experts are studying the handwriting of scientist Nicolaus Copernicus to determine if recently-discovered glosses, or notes written on the margins, in a book from the library of the Seminary of Warmia Metropolis "Hosianum" in Olsztyn, Poland were written by Copernicus or by someone else.

The incunabulum, or first edition, was known to have been owned by the scientist. "It is known that Copernicus’ handwriting changed with age, in his youth he wrote differently than in old age. These are tedious studies, we will focus primarily on comparing these words with other existing hand-written notes of Copernicus," said Prof. Zoja Jaroszewicz-Pieresławcew of the University of Warmia and Mazury.
