What is Cetus the god of?

Could you elaborate on the role and domain of Cetus, the deity? I'm curious to understand what sphere of influence or power he commands. Is he a god of the sea, the sky, or perhaps a more abstract concept? His name suggests a connection to the oceanic world, but I'm keen to learn if there's a deeper meaning or symbolism associated with his deity status. Your insight would be greatly appreciated in painting a clearer picture of Cetus' divine responsibilities.
