Evidence from the JEWISH SOURCES:
Talmud, b. Sanhedrin 43a: On the eve of the Passover Yeshu [Jesus] was hanged [or crucified]. ... Since nothing was brought forward in his favor he was hanged on the eve of the Passover.
The Amoa "Ulla" (Ulla was a disciple of Youchanan and lived in Palestine at the end of the third century) adds: "And do you suppose that for (Yeshu of Nazareth - Jesus) there was any right of appeal? He was a beguiler, and the Merciful One hath said: "Thou shalt not spare neither shalt thou conceal him." It is otherwise with Yeshu, for He was near to the civil authority.
Note here that the writers of the Talmud took their job seriously. These men were Jews who did not believe that Jesus was the Messiah. They were not Christians but they documented Christ's crucifixion.
EVIDENCE FROM ROMAN SOURCES:
Cornelius Tacitus in his Annals, xv. 44: Christus ... was executed at the hands of the procurator Pontious Pilate.
Lucian of Samosata: (Christ was) the man who was crucified in Palestine
Note here that these men were professional historians. They researched their work before publishing it. They also documented Christ's crucifixion.
Therefore, three types of witness all of whom are from the 1st or early 2nd century have been presented.
