In The Crucifixion with the Converted Centurion, Lucas Cranach the Elder chose to portray a scene of religious redemption. The crucified Christ, silhouetted against a darkened and troubled sky, is at the point of death; his last words from the cross are inscribed above him in German: VATER IN DEIN HET BEFIL ICH MEIN GAIST (Father, into thy hand I commend my spirit [Luke 23:46]). At that moment, a Roman centurion, astride a white charger, recognizes Christ's divinity and pronounces: WARLICH DISER MENSCH IST GOTES SVN GEWEST (Truly, this man was the Son of God [Mark 15:39]).
The theme of The Crucifixion with the Converted Centurion especially appealed to Protestants because it clearly illustrated the doctrine of salvation by faith alone, the central precept of their creed. The centurion, clothed in contemporary armor, symbolized the "Knight of Christ" who steadfastly defends his new-won belief despite all adversity.
From 1505 until his death, Cranach was the court painter to three successive electors of Saxony. He became close friends with Luther -- who lived in the Saxon town of Wittenberg -- and is considered the foremost artist of the Reformation.

The panel is composed of two boards with vertically oriented grain. Dendrochronological examination by Peter Klein provided dates of 1486-1531 and 1439-1530 for the individual boards and also indicated that both boards were from the same tree. At the top and bottom there are narrow, unpainted edges that have been apparently filled and overpainted at a later date. The left and right edges of the panel have been trimmed and a cradle attached. On the reverse strips of oak 0.38 cm wide have been set into the panel.
The painting is in good condition. There is a network of small cracks in the paint layer, which extends into the ground; this is most prominent in the front portion of the horse and extends upward into the area of Christ's drapery. There are some shallow scratches to the right of the horse and near Christ's torso. Areas of abrasion exist near the knees of the crucified figure at the left and in the hindquarters of the horse.
 The wood was identified as beech (sp.Fagus) by Peter Klein, examination report, 10 April 1987, and by the National Gallery's scientific research department, report, 15 July 1988, both in NGA curatorial files. The wood was erroneously identified as linden in exh. cat. Dresden 1899, which was repeated in Eisler 1977, 24.
