In addition to being a well-known portrait painter, Jordaens also employed his pencil in biblical, mythological, and allegorical subjects and even etched a number of plates. Although primarily a history painter, he also painted illustrations of Flemish proverbs, such as the "Old Sing so the Young Twitter", and depictions of Flemish festivals, for example "The King Drinks". Several of his works hint at a passion for animal painting. He often included a variety of animals, most likely drawn from life, including cows, horses, poultry, cats, dogs, and sheep. His life drawings of both animals and people were used and referenced throughout his life. After Rubens' death in 1640 Jordaens became Antwerp's new leading artist. Only after achieving this status did Jordaens receive royal commissions, predominantly from the north. He also received a commission from Ruben's heirs to finish a Hercules and an Andromeda for Philip IV of Spain.
