I know this is a joke/meme, but I sincerely think of the Roman Empire a surprising amount of times. I find myself obsessing over how Roman citizens were living just as complex lives as we are today, or about Marcus Aurelius’ life and philosophy, or about how the Republic fell and became a totalitarian state.
At least 2-3 times a day, I love their technology, the aqueducts the roads and the stone work. I love to think about post empire when the Germans Gauls and British were living around their ruins unable to build structures like they could. I think about the citizens and how similar their lives are to ours then how drastically it changed post empire. I think about how awful it must have been to be a slave in that time.
I got hooked on rome from Dan carlins hard core history series on the fall of the republic and he did another one on Cesar in Gaul.
