Crucifixion of Jesus:

According to the canonical gospels, Jesus, whom Christians believe to be the Son of God as well as the Messiah (Christ), was arrested, tried, and sentenced by Pontius Pilate to be scourged, and finally crucified by the Romans. Jesus was stripped of his clothing and offered wine mixed with gall to drink, before being crucified. He was then hung for six hours (according to Mark's Gospel) between two convicted thieves. During this time, the soldiers affixed a sign to the top of the cross stating "Jesus of Nazareth, King of the Jews" in three languages. They then divided his garments among them, but cast lots for his seamless robe. After Jesus' death they pierced his side with a spear to be certain that he had died. The Bible records seven statements that Jesus made while he was on the cross, as well as several supernatural events that occurred.
