oubliette?? demimonde?? either way, we're stuck

Star Trek: Voyager

also apparently this rock art dates across multiple periods spanning thousands of years? but i couldn't find much detail on that so i can't give specifics

but yeah, this isn't just a memory of giraffes, but of giraffes now absent encountered by people just 2000 years (the difference between the late roman republic and today) out of the ice age, in a climate unfamiliar to any of the hundred billion people born since the desertification of the sahara drove the ancient egyptians to the nile, near the start of the agricultural revolution

the time between this and the birth of the sahara was nearly as long as the time between the birth of the sahara and now, in which all recorded history is contained, and all languages we can recognise at all - the language and culture of these people would be totally alien to current libyans, twice the difference between the oldest european language and english, predating all but libya's mountains!
