Pontius Pilate was the fifth prefect of the Roman province of Judaea, from AD 26–36. He served under Emperor Tiberius, and is best known for presiding over the trial of Jesus and ordering his crucifixion.  The sources for Pilate’s life are an inscription known as the Pilate Stone, which confirms his historicity and establishes his title as prefect; a mention by Tacitus; Philo of Alexandria; Josephus; the four canonical gospels; the Gospel of Nicodemus; the Gospel of Marcion; and other apocryphal works. The first physical evidence relating to Pilate was discovered in 1961, when a block of limestone, the Pilate Stone, was found in the Roman theatre at Caesarea Maritima.  The procurators’ and prefects’ primary functions were military, but as representatives of the empire they were responsible for the collection of imperial taxes, and also had limited judicial functions.
