In Finniс mythology, the one who accompanies into the Kingdom of the Dead, to the underground river Toonela, is Toonekurg - the heron, the stork - Est. kurg, kure, Fin. kurki, Lapp. guorga, Nenets χǝŕo, Selkup. k͔ara, Matori körüh - “the marsh crane, heron, stork” - which corresponds to the Eng. heron, Welsh garan, Old French hairon, Dan. heire.
It is noteworthy that in Egyptian mythology there was a heron named Bennu, which personified the resurrection from the dead, and was depicted on a boat with an oar.
In Slavic languages the verb associated with burial is хоронить, horonit’ - “to bury”; while the newborn children are believed to be brought back by a stork.
Charon, Χάρων is not a Greek name, but was incorporated into the Greek myths from older myths and believes. The Greeks already depicted him as a man, thus loosing the memory of the shamanistic connections to animals in Old Europe.
