(Baldr had the greatest ship ever built, named Hringhorni.)

"According to Gylfaginning, following the murder of Baldr by Loki, the other gods brought his body down to the sea and laid him to rest on the ship. They would have launched it out into the water and kindled a funeral pyre for Baldr but were unable to move the great vessel without the help of the giantess Hyrrokkin, who was sent for out of Jötunheim. She then flung the ship so violently down the rollers at the first push that flames appeared and the earth trembled, much to the annoyance of Thor.

Along with Baldr, his wife Nanna was also borne to the funeral pyre after she had died of grief. As Thor was consecrating the fire with his hammer Mjolnir, a dwarf named Litr began cavorting at his feet. Thor then kicked him into the flames and the dwarf was burned up as well." (Wikipedia)

The greatest ship of all ought to be Argo Navis at the bottom of the sea. If a ship was put on fire, then it would surely sink. Possibbly Thor with his hammer could correspond to the figure in Ga2-1:

Thor certainly corresponded to Jupiter (Father Light) and the symbol for Jupiter was according to the Babylonian map at 'noon':

Why was the ship of Baldr put on fire? This could be a consequence of changing the orientation 90º to the right - corresponding to the change of the orientation of the Milky Way from 'time zero' in the Golden Age to midsummer in modern times. It meant a change from the horizontal plane through the equinoxes to the vertical pole through the solstices, with the June solstice as a place of much heat.

Notably Archimboldo painted his 'Man of Fire', who comes after the flowery spring, with his head resting in a kind of metallic contraption, as if his head has been severed from his body.

In Ga2-22 manu rere has a rising fish at left = in the past. The season of the sea (winter rains) was in the past and a high clear summer sky should arrive.

There was a dwarf named Litr who 'cavorted' at the feet of Thor, annoying him. Wikipedia says the name means 'colour'. I guess it could refer to the rainbow, a phenomenon which occurs where the Sun (summer) and the Rain (winter) join in spring.
