There was once a fisherman who lived with his wife in a pigsty, close by the seaside. The fisherman used to go out all day long a-fishing; and one day, as he sat on the shore with his rod, looking at the sparkling waves and watching his line, all on a sudden his float was dragged away deep into the water: and in drawing it up he pulled out a great fish. But the fish said, ‘Pray let me live! I am not a real fish; I am an enchanted prince: put me in the water again, and let me go!’ ‘Oh, ho!’ said the man, ‘you need not make so many words about the matter; I will have nothing to do with a fish that can talk: so swim away, sir, as soon as you please!’ Then he put him back into the water, and the fish darted straight down to the bottom, and left a long streak of blood behind him on the wave.

When the fisherman went home to his wife in the pigsty, he told her how he had caught a great fish, and how it had told him it was an enchanted prince, and how, on hearing it speak, he had let it go again. ‘Did not you ask it for anything?’ said the wife, ‘we live very wretchedly here, in this nasty dirty pigsty; do go back and tell the fish we want a snug little cottage.’

The fisherman did not much like the business: however, he went to the seashore; and when he came back there the water looked all yellow and green. And he stood at the water’s edge, and said:

‘O man of the sea!
Hearken to me!
My wife Ilsabill
Will have her own will,
And hath sent me to beg a boon of thee!’
