In the Problemata, a text contentiously credited to Aristotle, the philosopher tells how his student Alexander the Great descends to the depths of the sea in “a very fine barrel made entirely of white glass”, as a later poet would put it. The reasons for this descent differ across time. For some, it was to scout submarine defenses surrounding the city of Tyre during its siege. Others depict the Macedonian king met with a cruel vision of the great chain of being, stating, upon resurfacing, that “the world is damned and lost. The large and powerful fish devour the small fry”.

In one particularly elaborate version, Alexander submerges with companions — a dog, cat, and cock — entrusting his life to a mistress who holds the cord used to retrieve the bathysphere. However, during his dive, she is seduced by a lover and persuaded to elope, dropping the chains that anchor Alexander and his animal companions to their boat. Through a gruesome utility, the pets help him survive: the cock keeps track of time in the lightless fathoms, the cat serves as a rebreather to purify the vessel’s atmosphere, and the poor hound’s body becomes a kind of airbag, propelling Alexander back to the sea’s surface.
