Six onion-roof towers supporting heavens

[Koen G]

I don't remember if this painting was discussed before, but I think it may be relevant (Pierre mentioned the painter in the swallowtail thread). It shows a ciborium (in the architectural sense) with six pillars that support the throne of God, i.e. the highest of the heavens.

Also various tiers, twelve apostles around. Middle rosette vibes.

The painting's wikipedia page shows a similar composition by Michele Giambono with five towers.

Interesting! That's actually four towers, the red one is one of the "Arma Christi", with the rooster on top. This separate pillar is also present in the painting I linked, but there it's less visible and green.
