No less a man than Julius Caesar was a friend to the jews, the subura where he grew up was home to Rome synagogue. He gave us relative autonomy in Judea, and it was said that jews mourned his passing for months in the city.
For me, Rome was an example of a whirlwind of multiculturalism built on seven hills, a place where not everyone could be a patrician, but everyone could contribute to the expansion of the limits of human endeavor.
Hadrian, you missed one. (Do I need to /s?)
