The Fountains
Notice the two columns: rightside up, these are Heron Fountains, featured here as an allegory to Judeo-Christianity. Heron’s invention has three sections - two lower, airtight capsules, and one open section which is where water shoots up and is collected in a dish, then drained down directly to the lower capsule. From the lowest capsule, a tube draws water up into the second area, and from there, a third tube draws water up into the top. The water is “drawn up” by the principal of air displacement, and “priming the pump” is required to get it started, which is just turning it upside down and back up again.
For the narrative, Heron stationed Prophets at each section - Isaac is the lowest section, Moses in the middle, and Jesus at the top. Heron is saying that God taught Isaac “how to be good,” taught Moses “how to not be bad,” and finally installed Jesus as the path to an automatic ascension from the second chamber. Heron is saying it is not enough to just be good, ascension necessarily requires learning by experience how to not be bad. There must be real repentance to ask for forgiveness, the pump must get primed.
He is also demonstrating that ascension is not first-come, first-served. As a drop of water enters the second chamber, it could be there for a while before it gets moved up. In counter, a drop of water might move up very quickly, but purely by chance.
Shooting water from the top of the fountain is also a way to shake out extra electrons from water. The electrons float up and seek combinations above the tertiary world, in clouds or vapor, or they might become lightning - even super lightning, which takes them into space! Applying one electron theory into this idea, things get interesting.
