You have a Guercino (”Squinter”) for 1619, 1642 and 1654. The third appears to be an aberation, and perhaps was a production of his Bologna workshop which opened in 1642. His traditional use of chiarascuro continued with his 1648 fantastical “The Persian Sibyl.” How his technique could change so rapidly between 1648 and 1654 is mystifying.
Thank you for your helpful post! I went back and looked at each Guercino, then found his ‘Persian Sybil’ also; it’s quite stunning.
The Guercino from 1654 (#11 above) is my favorite of the three, but yes, it’s style is different. The father’s expression says a great deal...
Good question regarding his changing styles; I know that etabeta could answer how styles change so much.
Grateful to all who raise questions, and those who teach!
