At that time no man hurt another, even if he found the murderer of his
father or brother, loose or bound. Theft and robbery were then unknown,
insomuch that a gold armlet lay for a long time untouched in
Jalangursheath.

Frothi chanced to go on a friendly visit to a certain king in Sweden,
named Fiolnir, and there purchased two female slaves, called Fenia and
Menia, equally distinguished for their stature and strength. In those
days there were found in Denmark two quern-stones of such a size, that
no one was able to move them, and these mill-stones were endued with
such virtue, that the quern in grinding produced whatever the grinder
wished for. The quern was called Grotti. He who presented this quern to
Frothi was called Hengikioptr (hanging-chops). King Frothi caused these
slaves to be brought to the quern, and ordered them to grind gold,
peace, and prosperity for Frothi. The king allowed them no longer rest
or sleep than while the cuckoo was silent or a verse could be recited.
Then they are said to have sung the lay called Grotta-Savngr, and before
they ended their song to have ground a hostile army against Frothi,
insomuch, that a certain sea-king, called Mysingr, arriving the same
night, slew Frothi, taking great spoil. And so ended Frothi's peace.

Mysingr took with him the quern, Grotti, with Fenia and Menia, and
ordered them to grind salt. About midnight they asked Mysingr whether he
had salt enough. On his ordering them to go on grinding, they went on a
little longer till the ship sank under the weight of the salt. A
whirlpool was produced, where the waves are sucked up by the mill-eye,
and the waters of the sea have been salt ever since.
