At a subsequent confederation, held at Lublin in June, Zebrzydowski was reinforced by another great nobleman, Stanislaus Stadnicki, called the Devil, who "had more crimes on his conscience than hairs on his head," and was in the habit of cropping the ears and noses of small squires and chaining his serfs to the walls of his underground dungeons for months at a time.
The upshot of his oratory was the summoning of a rokosz, or national insurrection, to Sandomir, which was speedily joined by the majority of the szlachta all over the country, who openly proclaimed their intention of dethroning the king and chastising the senate, and sent Stadnicki to Transylvania to obtain the armed assistance of Stephen Bocskay.
Casimir Stadnicki has treated of the period of the Jagiellons; and Szaraniewicz, professor at the university of Lemberg, has written on the early history of Galicia.
