An oil on canvas painting by Caravaggio, created in 1601–1602. It was painted for Vincenzo Giustinian(an aristocratic Italian art collector)

This painting is a reference to the Gospel of John's depiction of the Apostle Thomas, who refused to believe the resurrected Jesus had appeared to the ten other apostles until he could see and feel Jesus's crucifixion wounds himself.The painting shows in a demonstrative gesture how the doubting apostle puts his finger into Christ's side wound, the latter guiding his hand.

The composition of the picture is such that the viewer is directly involved in the event and feels the intensity of the process. The painting features heavy chiaroscuro(the use of strong contrasts between light and dark)
