From the article: "Who Said Jesus Existed"
"Because of his writings, the most famous of which are the Annals and Histories, {Tacitus} has been called the “greatest historian” of ancient Rome. Tacitus recorded at least one reference to Christ and two references to Christianity.
“Consequently, to get rid of the report, Nero fastened the guilt and inflicted the most exquisite tortures of 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 Judea, the first source of the evil, but even in Rome, where all things hideous and shameful from every part of the world find their center and become popular.” (Annals, 15.44)
Tacitus here affirms that a man named Christ did in fact exist, who “suffered the extreme penalty” (put to death) at the hand of Pontius Pilate during the reign of Tiberius. He also refers to Christians being named after “
Christus” (Latin for Christ) and that their “superstition” (belief in the resurrection) started in Judea and made its way all the way to Rome."
