During a visit to Sweden saw and bought as slaves to the two giants Fenia Menia and powerful muscles and bodies which had attracted his attention. Back home he ordered his two new maids who grind gold, peace and prosperity. The women worked happily until the king's coffers were overflowing gold and abundant peace and prosperity in their domains. But the king, in his greed, not even allowed their servants to rest, so they retaliated by grinding a war, killing the king at the hands of the Vikings. Mysinger
The Viking king took the two stones and the maids and embarked on his ship, ordering the servants to grind salt, which was a very popular product at that time. But the Viking king became so greedy as the king Frodi, leaving the women to rest, so that as punishment, as was the amount of salt ground in the end its weight sank the boat. A consequence of this large amount of salt, the sea became salty.
