Socrates on dying and the swans of Apollo

Socrates wrote:

"...when the swans feel that the time has come for them to die, they sing
more loudly and sweetly than they have sung in all their lives before,
for joy that they are going away into the presence of the god whose
servants they are. I believe that the swans, belonging as they do to
Apollo, have prophetic powers and sing because they know the good
things that await them in the unseen world, and they are happier on
that day than they have ever been before. Now I consider that I am in
the same service as the swans, and dedicated to the same god, and that
I am no worse endowed with prophetic powers by my master than they
are, and no more disconsolate at leaving this life."
