The Crucifixion by Fra Angelico (Guido di Pietro), tempera transferred to canvas, laid down on wood, gold ground, circa possibly 1440. To the left of the Crucifixion are shown Saints Monica, her son Augustine, and Peter Martyr; to the right are Saints Dominic, Francis, and Elizabeth of Hungary. This damaged but poignant picture was painted in the 1440s, when Fra Angelico and his workshop were decorating the convent of San Marco in Florence with a cycle of frescoes financed by Cosimo de'Medici. The picture may well have been painted for Cosimo and is listed in a 1492 inventory of the Medici Palace. As in the San Marco frescoes, saints born hundreds of years after the Crucifixion are shown experiencing the event as an extension of their meditations. According to the accounts in the New Testament, Jesus, whom Christians believe to be the Son of God as well as the Messiah, was arrested, tried, and sentenced by Pontius Pilate to be scourged, and finally crucified. Collectively referred to as the Passion, Jesus' suffering and redemptive death by crucifixion are the central aspects of Christian theology concerning the doctrines of salvation and atonement. Jesus' crucifixion is described in the four canonical gospels, referred to in the New Testament Epistles, attested to by other ancient sources, and is firmly established as a historical event confirmed by non-Christian sources, though there is no consensus on the precise details of what exactly occurred.
