Flavius Josephus 
Works of Flavius Josephus 

According to Wikipedia: ‘Josephus (37 – c.100 AD/CE), also Yoseph Ben Mattithyahu in Biblical Hebrew (Joseph son of Matthias) and Titus Flavius Josephus[3] was a 1st-century Romano-Jewish historian and hagiographer of priestly and royal ancestry who recorded 1st century Jewish history, such as the First Jewish–Roman War which resulted in the Destruction of Jerusalem in 70 AD. He has been credited by many as recording some of the earliest history of Jesus Christ outside of the gospels, this being an item of contention among historians. Josephus was a law-observant Jew who believed in the compatibility of Judaism and Graeco-Roman thought, commonly referred to as Hellenistic Judaism. His most important works were The Jewish War (c. 75 AD/CE) and Antiquities of the Jews (c. 94 AD/CE). The Jewish War recounts the Jewish revolt against Roman occupation (66–70). Antiquities of the Jews recounts the history of the world from a Jewish perspective for a Roman audience. These works provide valuable insight into 1st century Judaism and the background of Early Christianity.’
