I came across this quote from Seneca:
Loco non tui si non ubi es.
It was translated as "A place is not yours if you're not there."
This seems a little strange. If you leave your home for a while, it's not yours? Is it correctly translated? Perhaps he was referring to Rome's claim to parts of its vast empire and the need to maintain a presence rather than rely on the loyalty of local rulers. This would be a great line for squatters to write on the walls someone's vacation home.
