Consider the firmament and its zodiak: We have no idea of the origins of the names: the lion, the bear, the twins... They are shrouded in ancient antiquity and remain constant... They point to a changeless Creator, to whom we are less than ants. He rules and reigns over the affairs of men, allowing good and evil threads in the grand tapestry of history which will only be seen whole when it is completed.
Be careful with this. These symbols are occult & not from God. I have a link that addresses mingling truth with lies, but maybe tomorrow.
The broader point is, no one knows their origins. God himself references the bear and Pleides in Job. Read your Bible.
