More influence from Ezekiel’s vision (see yesterday’s post) can be found in the “Flammarian engraving.”

“A naïve missionary of the Middle Ages even tells us that, in one of his voyages in search of the terrestrial paradise, he reached the horizon where the earth and the heavens met, and that he discovered a certain point where they were not joined together, and where, by stooping his shoulders, he passed under the roof of the heavens.” Camille Flammarion, L’atmosphère: météorologie populaire, 1888.
