Jesus' Crucifixion In Art

This fresco, painted on the walls of Santa Maria Novella in Florence, is considered to be Masaccio's masterpiece. The patrons who commissioned the work are shown kneeling at the forefront of the painting, however they cannot be identified with certainty. The painting depicts the crucifixion of Christ, with the customary figures of the Virgin and St John at the foot of the cross. However, the scene defies Renaissance convention in so many ways that it has remained an enigma, despite being studied by scholars for hundreds of years. The painting is known as The Holy Trinity (Santa Trinità) due to its depiction of Christ with God behind him, and the white dove of the Holy Spirit hovering between their heads. Although a figurative depiction of God was not a religious taboo at the time, he would usually have been depicted in a non-earthly realm, representing the heavens, rather than in the concrete space of the church. 

This Fresco is in the  Church of Santa Maria Novella, Florence 

The impenitent thief is a man described in the New Testament account of the Crucifixion of Jesus. In the Gospel narrative, two bandits are crucified alongside Jesus. In the first two Gospels (Matthew and Mark), they both join the crowd in mocking him. In the version of the Gospel of Luke, however, one taunts Jesus about not saving himself and them, and the other (known as the penitent thief) asks for mercy.
