"Since I must die," he said, "before I choose the manner of my death, I
conjure you on your honour to tell me if you really were in that vase?"
"Yes, I was," answered the genius.
"I really cannot believe it," said the fisherman. "That vase could not
contain one of your feet even, and how could your whole body go in? I
cannot believe it unless I see you do the thing."
Then the genius began to change himself into smoke, which, as before,
spread over the sea and the shore, and which, then collecting itself
together, began to go back into the vase slowly and evenly till there
was nothing left outside. Then a voice came from the vase which said
to the fisherman, "Well, unbelieving fisherman, here I am in the vase;
do you believe me now?"
The fisherman instead of answering took the lid of lead and shut it
down quickly on the vase.
"Now, O genius," he cried, "ask pardon of me, and choose by what death
you will die! But no, it will be better if I throw you into the sea
whence I drew you out, and I will build a house on the shore to warn
fishermen who come to cast their nets here, against fishing up such a
wicked genius as you are, who vows to kill the man who frees you."
At these words the genius did all he could to get out, but he could
not, because of the enchantment of the lid.
Then he tried to get out by cunning.
"If you will take off the cover," he said, "I will repay you."
"No," answered the fisherman, "if I trust myself to you I am afraid you
will treat me as a certain Greek king treated the physician Douban.
Listen, and I will tell you."
