Poseidon

Poseidon is angry.

You obviously can't blame Poseidon for sinking the Titanic.

Thus in vase pictures, when Poseidon upheaves the island of Cos to overwhelm the Giant Polybotes, the island is represented as an immense mass of rock; the parts which have been under water are indicated by a dolphin, a shrimp, and a sepia, the parts above the water by a goat and a serpent.

Neptune was the roman equivalent of Poseidon.
