It's interesting that people from long ago were often only known for their only name, such as Socrates, Jesus, and Constantine I. But in our current society, almost everyone has a first name and a last name, with some having a middle name.
I'm curious what culture first brought forth the concept of last names. I've heard that last names were used to identify people who worked specific positions in society, like the last names Carpenter and Smith, but what about many other last names which bear no resemblance to jobs that may have been held by people? Examples, last names like Parker (was it a person that parked carriages/cars?).
