been) born in Judea. Other research points to a 1991 report from the Royal Astronomical Society, which mentions that Chinese astronomers noted a "comet" that lasted 70 days in the Capricorn region of the sky, in March of 5 BC. Authors Dugard and O'Reilly consider this event as the likely Star of Bethlehem. However, there are many possible phenomena and none seems to match the Gospel account exactly. Years of preaching Reign of Tiberius and the Gospel of Luke One method for the estimation of the date of the beginning of the ministry of Jesus is based on the Gospel of Luke's specific statement in Luke 3:1–2 about the ministry of John the Baptist which preceded that of Jesus: Now in the fifteenth year of the reign of Tiberius Caesar, Pontius Pilate being governor of Judaea, and Herod being tetrarch of Galilee, and his brother Philip tetrarch of the region of Ituraea and Trachonitis, and Lysanias tetrarch of Abilene, in the highpriesthood of Annas and Caiaphas, the word of God came unto John the son of Zacharias in the wilderness. The reign of Tiberius began on the death of his predecessor Augustus in September AD 14, implying that the ministry of John the Baptist began in late AD 28 or early AD 29. Riesner's alternative suggestion is that John the Baptist began his ministry in AD 26 or 27, because Tiberius ruled together with Augustus for two years before becoming the sole ruler. If so, the fifteenth year of Tiberius' reign would be counted from AD 12. Riesner's suggestion is however considered less likely, as all the major Roman historians who calculate the years of Tiberius' rule – namely Tacitus, Suetonius and Cassius Dio – count from AD 14 – the year of Augustus' death. In addition, coin evidence shows that Tiberius started to reign in AD 14. The New Testament presents John the Baptist as the precursor to Jesus and the Baptism of Jesus as marking the beginning of Jesus' ministry. In his sermon in Acts 10:37–38, delivered in the house of Cornelius the centurion, Apostle Peter refers to what had happened "throughout all Judaea, beginning from Galilee, after the baptism which John preached" and that Jesus had then gone about "doing good". Jesus' baptism account is followed directly by his 40 day fast and ordeal. The Temple in Jerusalem and the Gospel of John Another method for estimating
