The historian known to
         posterity by the Latinized name Josephus was a member of Jerusalem's
         priestly aristocracy who, at age 30, was taken hostage in the great Jewish
         revolt against Rome (66-70 CE) 
         & spent the rest of his life in Roman
         circles as a protégé of three emperors [Vespasian,
         Titus
         & Domitian].
         His constant need to explain his role in the unsuccessful Jewish uprising
         that climaxed with the destruction of the Jerusalem temple led him to
         publish four works [in Greek] that are our prime source for information
         about events that shaped the history of Jews of the second temple period.
      Joseph bar Matthew [Greek:
         Matthias], as Josephus was originally known, was born soon after Caligula
         became Roman emperor (37/38 CE). 
         He was one of two sons of a Jewish priest
         who claimed  descent from the
          Hasmonean family of priests who had won
         Jewish independence from the Greco-Syrian empire two centuries earlier. A
         precocious youth with a thirst for learning, Josephus claims that by the
         time he was 14 he was already consulted on legal problems by Jerusalem's
         chief priests [Life
         8]. At age 16 he began three years of intense religious training.
         After basic introduction to the principles of the three primary  Judean
         factions [Pharisees, Sadducees & Essenes], Josephus attached himself
         to an ascetic hermit [Bannus] who was an advocate of a natural lifestyle
         in the wilderness of Judea.
         When he returned to Jerusalem (57 CE), 
         he associated himself with the
         majority party of the Pharisees. Factionalism was intensifying in Judea,
         however, with an increase of demagogues & revolutionary bands. Roman
         prefects, responsible for maintaining social order, reacted swiftly &
         ruthlessly to suppress dissent from any quarter. When Gessius
         Florus sent some priests that
         Josephus knew in chains to Rome 
 (64 CE), he followed to
         petition the emperor [Nero] to release them. 
         The emperor's consort,
         Poppea,
         introduced the 26 year old Jewish aristocrat to the imperial court &
         supported his cause. This successful mission left Josephus favorably
         impressed by the grandeur & power of Rome & with a first-hand
         familiarity with imperial circles that few of his contemporary Jews could
         match.
      By the time he returned to
         Jerusalem, however, the Jewish revolt had already begun (66 CE). 
         A radical faction [led by Menachem, a son of Judah "the
         Galilean" who had led a  tax revolt against 
         Rome 60 years earlier] had
         seized the fortress of Antonia, forcing priests to seek refuge in the
         temple below. As rival revolutionary factions vied for control of
         Jerusalem & murdered their opponents [including Menachem],
         Josephus & other priests aligned themselves with the cause of
         independence. The rebels, encouraged by their decisive defeat of Roman
         troops that the governor of Syria [Cestius
         Gallus] dispatched to pacify the
         city, sent Josephus to fortify Galilee
         & persuade Galileans to join the revolt. Giscala [Gush cHalav]
         & other towns in rural northwestern Galilee were already centers of
         revolt. But the Romanized cities of the more populated southern tier [Sepphoris
         & Tiberias]
         were reluctant to join a war with Rome. The rebels in Jerusalem apparently
         thought that Josephus, as an aristocrat with success as a negotiator in
         Rome, could persuade hesitant Galileans to support the cause of
         independence. He met little success either as a negotiator or a military
         leader, however, characteristically blaming others for his failures. The
         residents of the old Galilean capitol, Sepphoris---whose city had been
         destroyed by Roman armies 72 years earlier, in the  uprising following
         Herod's death (4 BCE)---would not be part of a rebellion. 
         The population
         of Tiberias---the lakeside metropolis built by Herod's
         son, Antipas---was
         divided but unwilling to accept Josephus as their leader. Josephus
         succeeded in fortifying the central Galilean city of Jotapata
         [Yodefat], but was fortunate to survive its capture. Upon his surrender, he
         predicted the man who defeated him [Vespasian]
         would become emperor of Rome, a prediction soon made possible by Nero's
         suicide (68 CE). 
         Taken to Jerusalem as a hostage, Josephus was eye-witness
         to the Roman siege. When Vespasian was called to Rome to become emperor
         (69 CE), he directed his 
         son Titus
         to continue the siege. Josephus was held in the Roman camp & witnessed
         the destruction of the temple (70 CE) that 
         had been the center of his
         family's life for generations.
      Taken to Rome after the war,
         Josephus was declared a freed man, granted Roman citizenship, provided a
         pension & lodging on Vespasian's estates. He adopted the family name
         of his imperial patrons & was thus known to Romans as Flavius
         Josephus. He was near the top of Vespasian's "civil list" of
         Roman citizens. He witnessed first-hand the rebuilding of Rome after Nero's fire
         (65 CE) & the erection
         of the Flavian monuments [Colosseum,
         the temple of Peace, the forum of Vespasian & the arch of Titus,
         depicting the conquest of the temple in Jerusalem]. He used his position
         both to support the cause of the Flavian emperors & to defend his own
         place as a fixture in their court. Though he gave his children gentile
         names, he remained dedicated to his Jewish heritage, spending years
         writing voluminous works to explain & glorify those who championed the
         laws of Moses to Romans who, in the wake of the Jewish revolt, regarded
         all Jews as lawless riff-raff & bandits. After his death a statue was
         erected to him & his works placed in the Roman public library, where
         they came to be a major source of information for all later historians:
         Christian, Jewish & secular [Eusebius, History of the Church
         3.9].
