Guercino
Painter and draftsman
(Cento, Italy, 1591 - 1666, Bologna, Italy)
ULAN note: Son of a laborer who transported wood. He was called Guercino (squinter), because he was cross-eyed or had a squint in his right eye. Reputedly self-taught early, then an apprentice in the shop of Benedetto Gennari. Patrons included the papal legate at Ferrara and the Archbishop of Bologna. He developed a classical style later in his career. After the death of Guido Reni, Guercino was the leading artist in Bologna. He is also known as a brilliant draftsman.
