Here is an interesting list from atheist.org.
They Should Have Noticed
John E. Remsburg, in his classic book The Christ: A Critical Review and Analysis of the Evidence of His Existence (The Truth Seeker Company, NY, no date, pp. 24-25), lists the following writers who lived during the time, or within a century after the time, that Jesus is supposed to have lived:
Josephus, Philo-Judæus, Seneca, Pliny Elder, Arrian
Petronius, Dion Pruseus, Paterculus, Suetonius,Juvenal
Martial, Persius, Plutarch, Pliny Younger,Tacitus
Justus of Tiberius, Apollonius, Quintilian, Lucanus
Epictetus, Hermogones Silius Italicus, Statius, Ptolemy
Appian, Phlegon, Phædrus, Valerius Maximus, Lucian
Pausanias, Florus Lucius, Quintius Curtius, Aulus Gellius
Dio Chrysostom, Columella, Valerius Flaccus, Damis
Favorinus, Lysias, Pomponius Mela, Appion of Alexandria, and
Theon of Smyrna
According to Remsburg, "Enough of the writings of the authors named in the foregoing list remains to form a library. Yet in this mass of Jewish and Pagan literature, aside from two forged passages in the works of a Jewish author, and two disputed passages in the works of Roman writers, there is to be found no mention of Jesus Christ." Nor, we may add, do any of these authors make note of the Disciples or Apostles - increasing the embarrassment from the silence of history concerning the foundation of Christianity.
