SYMBOLISM OF THE EAST & WEST
H. MURRAY- AYNSLEY
In Scandinavian mythology, a fabulous dog called Garmr was believed to guard the entrance to the infernal regions. Several of the northern nations of Europe believed the dead had to cross over water in boats to their future home. For this reason, in Scandinavia, bodies were sometimes buried in ships. A large vessel containing the bones and weapons of some deceased chief was found a few years ago near the Sonde Fjord in Norway. Sweden, too, has popular legends to the same effect. Thus, Odin is fabled to have conveyed the slain from Brahalla to Valhalla in a golden ship.
I would regard this text with a good deal of skepticism.
As a Norwegian, I don't understand what is meant by "Sonde Fjord in Norway". There is a region called Sunnfjord, formerly spelt Søndfjord, but this is actually not a fjord.
As to "Brahalla", my only guess -- probably wrong! -- is that it could refer to the Brahälla or Brahehälla castle ruins at Gränna in Sweden. But whether these have been tied to local myths about Norse gods, I have no idea. The castle dates back less than 350 years.
It seems that H. Murray-Aynsley couldn't spell Scandinavian names, but the rest may still be right. My guess is that "the Sonde Fjord" in Norway should be Sandefjord (which is a town and not a fjord). That fits with the "large vessel containing the bones and weapons of some deceased chief", which could be the Gokstad Ship (a viking ship found in a burial mound near Sandefjord).
For the Swedish case, I googled a couple of alternative spellings of "Brahalla". That led me to the Battle of Bråvalla, which took place around year 770. Maybe Brahalla should be Bråvalla? Battle of Brávellir - Wikipedia
