Or Jesus Christ, as he is more commonly known. Jesus was a religious teacher in first century Israel. Christians believe that he was the Son of God and that he rose from the dead when the Romans crucified him for stirring up unease among the Jews.

Hardy calls him the Nazarene here because he grew up in Nazareth and is sometimes referred to as Jesus of Nazareth.
