This is a medieval illustration depicting a fantastical scene at sea. A large, dark gray whale is being hoisted out of the water by ropes attached to two tall, cylindrical columns. On top of the whale, a figure with a crown is seated, seemingly controlling the creature. Above the whale, a small boat is occupied by three figures, also wearing crowns. They appear to be observing the whale being lifted. The sea is filled with various fish and other marine creatures, rendered in a whimsical style. On the shore, there are small trees and more fantastical creatures. The background is a deep blue, possibly representing the sky, with a lattice pattern. The overall style is characteristic of illuminated manuscripts, with flat perspectives and vibrant colors.
