This famous wood engraving appeared in Camille Flammarion’s book L’atmosphere: meteorologie populaire.
It depicts a medieval pilgrim who has somehow arrived at a place where the Earth and the dome of night touch, and — lo! — he is able to peak through into a celestial realm.
The same urge to discover something new is still alive today as we seek new ways through science and technology to solve human problems on earth such as sustainability.
