Love this…What are the columns in the top of the firmament?

Possibly this: "The Eight Pillars Located in the eight cardinal directions, they are a group of eight mountains or pillars which have been thought to hold up the sky. They are symbolically important as types of axis mundi and cosmology. Their functions ranged from pillars which functioned to hold apart the Earth and the Sky (or Heaven), as ladders allowing travel between the two".
