Some of the Roman writers tried to rationalize the story of Atlas holding up the sky by equating Atlas to mountains — specifically, the Atlas Mountains. They accomplish this using Medusa’s head.
The gist of the tale is that Perseus passed near Atlas’ location — at the far west of the known world (i.e. continental Europe and Northern Africa) — after slaying Medusa and asked for lodging and protection for the night. Atlas was rude and demanded Perseus to leave, prompting Perseus to expose the Titan to Medusa’s head and turn him into the mountain range. At no point, at least in any source that I know of, did Atlas explicitly ask to be turned to stone.
In lists of Roman Emperors, Theodosius is far from the most notable. One historian noted that this son of an emperor killed for high treason "veered disconcertingly between opposites—febrile activity and indolent sluggishness, a simple soldierly life and the splendors of the court." But this little-known emperor forever changed the course of Christian history not in one way, but in two. He used his power to officially enforce orthodox Christianity, but ended up placing his power under that of the church, setting a standard for more than a millennium.
