The wife of a Tsar.

He went on and on till he came to a city where all the people were
weeping and all the houses were hung with black cloth. And he said to
them, "Why do ye weep, and why are all your houses hung with
black?"--And they answered, "Because there's a Dragon here who eats
the people, and it has come to such a pass with us that to-morrow we
must give him our Princess for dinner."--"Nay, but ye shall not do
this thing," said he, and, with that, he set out for the cavern where
the Dragon lived, and tethered his horse there and slept by the side
of the cavern all night. And the next day, sure enough, the Princess
was brought to the mouth of the cavern. She came driving thither in a

his six heads and began to wriggle out of the cavern; but the Prince
attacked him with his huge broadsword, a full fathom long, which the
Lord had given him, and chopped off all the Dragon's six heads, and
the rock fell upon the Dragon's body and crushed it to pieces. Then
the Prince gathered up the six dragon-heads and laid them on one side,
and cut out the six lolling tongues and tied them in his handkerchief,
and told the Princess to go back to her palace, for they could not be
married for a year and twelve weeks, and if by that time he did not
appear, she was to marry another, and with that he departed. Then the
coachman of the Princess came up to the place and saw the six heads of
the Dragon, and took them up and said to the Pri
