This painting is mentioned several times in Brueghel's letters. He sent it along with Allegory of Fire and a St. Anthony that's now lost to Borromeo in Dec. 1608.
This is a rarity among Jan's paintings for Borromeo in that it was replicated many times; usually the works he sent to Milan remained unique.
