Abraham Casting Out Hagar and Ishmael
Giovanni Francesco Barbieri, Abraham Casting Out Hagar and Ishmael, 1657. Oil on canvas, Pinacoteca di Brera, Milan.
Barbieri (1591–1666), is best known as Guercino or Il Guercino. Guercino is Italian for squinter, a nickname that was given to him because he was cross-eyed. He was an Italian Baroque painter from the region of Emilia.
Guercino was very famous in his lifetime and became quite wealthy.
He was remarkable for the extreme rapidity of his execution—he completed no fewer than 106 large altar-pieces for churches, and an additional 144 paintings.
