The image is a photograph of a plaque on a wooden shelf. The plaque is titled "Water Jar with Dionysos and Poseidon" and is written in black text on a white background. The text is divided into two sections. 

On the left side of the plaque, there is a black and white illustration of a vase with a handle and a spout. The vase is made of terracotta and has a handle on one side. On the right side, there are two illustrations of Poseidon's hand, one of which is holding a spear and the other of which has a shield. The illustrations are accompanied by text that explains that Poseidon was made in the Eastern Mediterranean, Greek, and bronze.

At the bottom of the image, it reads "Poseidon's raised hand probably once held a trident, three-pronged spear, and his left hand may have a dolphin or a ship's ornament. Although Poseidon is a symbol of the sea god, Poseidon has a crown of water plants and is often used as a symbol for the sea. He is also known as Poseidon, a Greek god of the underworld.
