Here are a few early non biblical historical references to Jesus.
Josephus, Jewish historian, Antiquities. 18.3, 18.64
Book XVIII “3. Now there was about this time Jesus, a wise man, if it be lawful to call him a man; for he was a doer of wonderful works, a teacher of such men as receive the truth with pleasure. He drew over to him both many of the Jews and many of the Gentiles. He was [the] Christ. And when Pilate, at the suggestion of the principal men amongst us, had condemned him to the cross, those that loved him at the first did not forsake him; for he appeared to them alive again the third day; (10) as the divine prophets had foretold these and ten thousand other wonderful things concerning him. And the tribe of Christians, so named from him, are not extinct at this day.”
Cornelius Tacitus, (AD 55 - 117)The Annals (15.44) Ancient roman Historian and Politician
“Such indeed were the precautions of human wisdom. The next thing was to seek means of propitiating the gods, and recourse was had to the Sibylline books, by the direction of which prayers were offered to Vulcanus, Ceres, and Proserpina. Juno, too, was entreated by the matrons, first, in the Capitol, then on the nearest part of the coast, whence water was procured to sprinkle the fane and image of the goddess. And there were sacred banquets and nightly vigils celebrated by married women. But all human efforts, all the lavish gifts of the emperor, and the propitiations of the gods, did not banish the sinister belief that the conflagration was the result of an order. Consequently, to get rid of the report, Nero fastened the guilt and inflicted the most exquisite tortures on a class hated for their abominations, called Christians by the populace. Christus, from whom the name had its origin, suffered the extreme penalty during the reign of Tiberius at the hands of one of our procurators, Pontius Pilatus, and a most mischievous superstition, thus checked for the moment, again broke out not only in Judæa, the first source of the evil, but even in Rome, where all things hideous and shameful from every part of the world find their centre and become popular. Accordingly, an arrest was first made of all who pleaded guilty; then, upon their information, an immense multitude was convicted, not so much of the crime of firing the city, as of hatred against mankind. Mockery of every sort was added to their deaths. Covered with the skins of beasts, they were torn by dogs and perished, or were nailed to crosses, or were doomed to the flames and burnt, to serve as a nightly illumination, when daylight had expired.
Nero offered his gardens for the spectacle, and was exhibiting a show in the circus, while he mingled with the people in the dress of a charioteer or stood aloft on a car. Hence, even for criminals who deserved extreme and exemplary punishment, there arose a feeling of compassion; for it was not, as it seemed, for the public good, but to glut one man’s cruelty, that they were being destroyed.”
Lucian de Samosata, Greek, (AD 120-180) rhetorician (somewhat like a trial attorney). Politician, historian, itinerant lecturer.(The Death of Peregrine, 11-13, 16)
“It was now that he came across the priests and scribes of the 11 Christians, in Palestine, and picked up their queer creed. I can tell you, he pretty soon convinced them of his superiority; prophet, elder, ruler of the Synagogue–he was everything at once; expounded their books, commented on them, wrote books himself. They took him for a God, accepted his laws, and declared him their president. The Christians, you know, worship a man to this day,–the distinguished personage who introduced their novel rites, and was crucified on that account. Well, the end of it was that Proteus was arrested and thrown12 into prison. This was the very thing to lend an air to his favourite arts of clap-trap and wonder-working; he was now a made man. The Christians took it all very seriously: he was no sooner in prison, than they began trying every means to get him out again,–but without success. Everything else that could be done for him they most devoutly did. They thought of nothing else. Orphans and ancient widows might be seen hanging about the prison from break of day. Their officials bribed the gaolers to let them sleep inside with him. Elegant dinners were conveyed in; their sacred writings were read; and our old friend Peregrine (as he was still called in those days) became for them “the modern Socrates.” In some of the Asiatic 13 cities, too, the Christian communities put themselves to the expense of sending deputations, with offers of sympathy, assistance, and legal advice. The activity of these people, in dealing with any matter that affects their community, is something extraordinary; they spare no trouble, no expense. Peregrine, all this time, was making quite an income on the strength of his bondage; money came pouring in. You see, these misguided creatures start with the general conviction that they are immortal for all time, which explains the contempt of death and voluntary self-devotion which are so common among them; and then it was impressed on them by their original lawgiver that they are all brothers, from the moment that they are converted, and deny the gods of Greece, and worship the crucified sage, and live after his laws. All this they take quite on trust, with the result that they despise all worldly goods alike, regarding them merely as common property.”
