is under the jurisdiction of Herod Antipas. Given that Herod was in Jerusalem at that time, Pilate decided to send Jesus to Herod to be tried. This episode is described only in the Gospel of Luke (23:7–15). While some scholars have questioned the authenticity of this episode, given that it is unique to the Gospel of Luke, the International Standard Bible Encyclopedia states that it fits well with the theme of the gospel. Herod Antipas, a son of Herod the Great, was born before 20 BC and was exiled to Gaul in the summer of AD 39 following a lengthy intrigue involving Caligula and Agrippa I, the grandson of his father. This episode indicates that Jesus' death took place before AD 39. Conversion of Paul Another approach to estimating an upper bound for the year of death of Jesus is the estimation of the date of conversion of Paul the Apostle which the New Testament accounts place some time after the death of Jesus. Paul's conversion is discussed in both the Letters of Paul and in the Acts of the Apostles. In the First Epistle to the Corinthians (15:3–8), Paul refers to his conversion. The Acts of the Apostles includes three separate references to his conversion experience, in Acts 9, Acts 22 and Acts 26. Estimating the year of Paul's conversion relies on working backwards from his trial before Junius Gallio in Achaea, Greece (Acts 18:12–17) around AD 51–52, a date derived from the discovery and publication, in 1905, of four stone fragments as part of the Delphi Inscriptions, at Delphi across the Gulf from Corinth. The inscription preserves a letter from Claudius concerning Gallio dated during the 26th acclamation of Claudius, sometime between January 51 and August 52. On this basis, most historians estimate that Gallio (brother of Seneca the Younger) became proconsul between the spring of AD 51 and the summer of AD 52, and that his position ended no later than AD 53. The trial of Paul is generally assumed to be in the earlier part of Gallio's tenure, based on the reference (Acts 18:2) to his meeting in Corinth with Priscilla and Aquila, who had been recently expelled from Rome based on Emperor Claudius' expulsion of Jews from Rome, which is dated to AD 49–50. According to the New Testament, Paul spent eighteen months in Corinth, approximately seventeen years after his conversion. Galatians 2:1–10 states that
