An obedient son, Seth (shown twice) listens to his dying father’s last wish, dons his cap and sets out the door to fulfill Adam’s request, in this 15th-century illumination from the Book of Hours of Catherine of Cleves. According to extrabiblical legend, the dying man sent his youngest son back to paradise to obtain anointing oil from the Tree of Knowledge.
