The Gero Cross or Gero Crucifix ("Gero-Kreuz" in German), of around 965–970, is the oldest large sculpture of the crucified Christ north of the Alps, and has always been displayed in Cologne Cathedral in Germany. It was commissioned by Gero, Archbishop of Cologne, who died in 976, thus providing a terminus ante quem for the work. It is carved in oak, and painted and partially gilded – both have been renewed. The halo and cross-pieces are original, but the Baroque surround was added in 1683. The figure is 187 cm high, and the span of the arms is 165 cm.
The Gero Cross is important to medieval art for the unique way it depicts Christ. The figure appears to be the earliest, and finest, of a number of life-size German wood sculpted crucifixions that appeared in the late Ottonian or early Romanesque period, later spreading to much of Europe. It is the first monumental depiction of the crucified Christ on the Cross and the first monumental sculpture dating from this period. Standing over six feet tall, it was one of the largest crosses of its time. Additionally, it appears to be the oldest Western depiction of a dead Christ on the cross; in most earlier depictions, Christ holds his head erect and looks straight ahead, or in some Carolingian examples looks down at the Virgin at the foot of the cross.
The shape of the Gero Cross is traditional to Carolingian religious art. However, this piece puts extra emphasis on the suffering of Jesus Christ's crucifixion, with the slumped head, lifeless body, and closed eyes. Other depictions are idealized and do not show Christ as vulnerable and disfigured. This was a major influence on later crosses, especially in 11th-century Germany, where you see more crosses that follow this rounded, natural style. The slumped head and twisted body, which arises as the hands are nailed to the cross at different heights, are found neither in Carolingian nor Byzantine art, and were to be slow to influence Western depictions, although the long hair spread over the shoulders is found in some Carolingian works. The style of the Gero Cross shows a great deal of Byzantine influence, most likely stemming from Otto II's marriage to a Byzantine princess, creating a cultural link between the Catholic Church and the Byzantine Empire. In crucifixions of the Gothic period, a still more slumped and curved figure of Christ, with knees bent sideways, was to become the standard depiction.
