We speak here about towers and containers but today it came to me that yet another third inspiration is possible.
Meet the
seven candlesticks (or lampstands) of Apocalypse:
Revelation 1:12-13 "I turned around to see the voice that was speaking to me. And when I turned I saw seven golden lampstands, and among the lampstands was someone like a son of man,"
Yes, there are 6 and not 7 of these towers/containers in the Rosette page but the artist could be imprecise.
I don't claim they and lampstands but would like to add it as an option.
