To the left, the Venus of Willendorf, a 10.8 cm high stone statuette dating from the Paleolithic era, 30-27 kyr. To the right, the first anthropomorphic design for an atmospheric diving suite built by the Carmagnolle brothers of Marseilles, France in 1882.

The Carmagnolle brothers diving suite is the stuff of steampunk fantasy, but perhaps so situating it is time-out-of-joint in the wrong direction. Instead of designating it as a paleo-future, it is more properly a parachronism: perhaps we should call it the Venus (Ares) of Marseilles (with the Venus of Willendorf as old stone punk).
