I only now read that Castor and Pollux as the star constellation Gemini were of help to sailors, and that of the twins the other was mortal and the other immortal. How fitting to the ancient myth, that thousands of years later, of the re-emerged Castor and Pollux, Endrass died very young, and Topp lived nearly a hundred years. In the Greek myth the immortal twin gave half of his immortality to his dead brother. Now Topp and Endrass on the other hand, in the submarine enthusiast circles, they are as close to immortality as anything human can be.
