I looked at this link that Valis posted http://www.sonic.net/sentinel/naij3.html
The only provable historian to have written these things that mention Jesus, "the Christ" is that of Josephus. Although there are 2 references to him in his writings, only one is thought to have been done by him, that being the first bold in the following quote from the websight:
Jewish historian Flavius Josephus, a member of a priestly family and who became a Pharisee at the age of 19, became the court historian for Emperor Vespasian. In the Antiquities, he wrote about many persons and events of first century Palestine. He makes two references to Jesus. The first reference is believed associated with the Apostle James. "...he brother of Jesus, who was called Christ." He also wrote, "At this time there was a wise man who was called Jesus. And his conduct was good and (he) was known to be virtuous. And many people from among the Jews and other nations became his disciples. Pilate condemned him to be crucified and to die. And those who had become his disciples did not abandon his discipleship. They reported that he had appeared to them three days after his crucifixion and that he was alive, accordingly, he was perhaps the messiah concerning whom the prophets have recounted wonders." These historical writings predated the Old Testament. Josephus died in 97 A.D.There is an interesting rebutal to this ideal, that Josephus was confirming the existance of Jesus and can be found at

Jeff Lowder goes through all the arguements presented for each reference presented on the previous websight and presents an interesting counter to them.
