The sea God Proteus is depicted in classical mythology as a kindly, elderly deity whose time is mostly spent with seals and, when confronted will tell anyone whatever they want to know, including the future. That may well be in an ancient era when the seas were clean, but now Proteus is not so kindly disposed to humans... 

"I am Proteus a mighty God of the seas. I thank you for honouring me today, especially today as with the Furies I share the same day for my creation, so celebrate with me."

Proteus has dark hair and seems younger than many other sea Gods - they all look quite elderly but Proteus is only 40ish. He has quite a 'round' face, and like most other sea Gods has a beard but not as long and shaggy as the others and it is short and darkish, not white.  His eyes are blue/green. Most times he appears wearing a loin cloth around his waist.  Proteus is big built with very large feet.

"I now have many temples and am influencing the minds of mortals. Some are troubled one way or another, some are sick, some are just greedy and mean. I treat them all alike and bring my soothing presence into their mind, if not their conscious then their auric mind. It may take a little while but they will be influenced by my presence. The world will change for the better, this I promise.

The great oceans cover much of your planet, yet man does not respect either the seas or us. He lives in ignorance and it pleases him to do so. 
     In days when the Olympian faith was practised in several countries, before setting forth across the ocean, a sailor would pray to one of us. If possible he would go to a temple, offer us wine, fruit or flowers to appease us that he may have a safe journey. It depended on how we felt whether we granted this. Yet now man exploits the seas, doing much harm. He fishes by rod and line, by nets, by traps and by any means he can to make money from the creatures of the deep. Men are fishing not just for food but for sport and so many fish are caught by cruel hooks and are then thrown back because they are too small. 
     He drills for oil and seeks other minerals from the bed of the oceans; breaks down corals so that they can fetch big money for him and in return he pumps oil from his tanks, throws his waste materials into the sea. The seashores are littered with rubbish from ships. There are so many places where life will never be the same because of oil, and nuclear waste thrown onto the ocean bed. We are taking steps to stop all of this happening and in many ways making mortals suffer. 

The cruelty of men who kill the whales and the seals does not go unnoticed. It will stop and those in charge of this will be punished severely. All this will change. Mortals will live in peace, not only with themselves but with the creatures of the seas.
    A few fishermen now have given up this work and have taken positions where they will never hurt a living creature; yet some prefer to remain blind and deaf although they hear me. On one of the Pacific islands there is a group of what you call Evangelists. They travel from island to island recruiting the natives and are busy organising a fishing regatta, they call it. I shall endeavour to whip up strong seas, but this will only postpone this vile act. Those who delight in killing sea life will always die a horrible death. I am very old and wise; yet I can be young and very cruel.

More creatures dwell in the ocean than you could ever dream about. Places where mortals do not fish, do not pollute are so beautiful. Your world under the sea is the most beautiful place, provided mortals leave it alone. They will learn."
