Zeus turning into a SWAN or BULL
Domine > demon
Deus > Dzeus > Zeus (D > dz > z).
Deus is most likely derived from feminine ''DEATA'' > ''DEA'', meaning day(light).
If so, it means Orion.
A character turning into an animal = the beginning of an astrological age (or the first degrees of it).
The Swan constellation is Cygnus. The Bull = Taurus (not to be mistaken with the Water Bull = Apis bull, Ptah, Cancer).
Considering that Freyr is Cancer, then the correlation to both zodiac signs is apt.
One question that needs to be elucidated is whether Zeus means Orion or simply what Freyr did at a specific timeline (specified by him turning into an animal).
In case the name is attributed to Asare/Osiris?Caesar, too, then the distinction could be based on the colour of their energy.
Freyr is blue.
Asare is red.
