Lucian of Samosata (Greek: Λουκιανὸς Σαμοσατεύς, Latin: Lucianus; A.D. 120 - after A.D. 180) was a Roman rhetorician and satirist, writing in the Greek language, noted for his witty and scoffing nature.
I think this is a pretty cool name. I like it better than "Lucius" in any case. I know someone named Lucian, too, and I think he's Italian. His nickname is Luci (LOO-chee).
