A black figure vase painting of Poseidon (right) and Athena (left). In ancient Greek art, divinities always had certain characteristics that distinguished them from one another. Poseiden, like Zeus, is normally shown as throwing something, normally his trident. Here, he is holding his trident in his right hand. Athena, as seen before, is wearing a long gown, her snake robe, a spear, and a crested helmet.
