"High Priestess" Original artwork

Hello there. It has been a while.
I present to you one of the paintings I was working on in the past months. "High Priestess"

A few months ago I was at my father's place, talking about things. He was showing me what he was working on on the side. He forging a sword, had some engine or some sort of generator parts (or something like that). One of the things that he had on his workbench was the thing that you see on the bottom part of the painting. 2 rolls of blocks forming circles, in the middle, it had chocks that were supporting a long axis. I immediately took out my phone and started taking pictures. I Was telling dad what started emerging in my mind (this painting more or less). He got more hyped than I was, he brought out some lights, pointed towards the part. Got me a big white sheet of paper to use as a screen, and to make it easier.
Sometimes small interaction like that with somebody is like rocket fuel and it can last you months on an end. I'm smiling while writing that...

I have a fiction story about the painting my question is, would you guys like to read what's the story of the artwork?
