In the German town of Hamelin seems to have occurred the famous tale of the "Pied Piper", narrated by the famous Brothers Grimm.
Apparently, in 1284, all children vanished into thin air, and they had no more news. A plaque presented in that city reports the following words:
In 1284, June 26
day of San Giovanni e Paolo
by a piper dressed in all colors
130 children nts to Hamelin were led away and were lost
at Calvary in the hills.
A fact of this magnitude at the time seemed almost normal, especially considering the many Children's Crusade (http://it.wikipedia.org/wiki/Crociata_dei_bambini) matches to the Holy Land, whose actors, however, never arrived at their destination, only to be sold as slaves or more on the way to the Middle East.
Kind Regards, The King
