Historical and structural analyses indicate that True Cross relics cannot plausibly originate from the 1st-century wood of Jesus' crucifixion, and inventories of the distributed fragments show they lack physical authenticity.
This study critically re-examines the possibility that the wooden cross of Jesus has survived as a relic into the present. From a historical and structural perspective, the Roman practice of crucifixion in the 1st century CE made the preservation of such wood highly improbable: the patibulum (crossbeam) was reused by soldiers, while the stipes (upright post) remained fixed in execution grounds, soaked with blood and body fluids, and subject to decay. Early Christians did not venerate the cross as a sacred object; instead, they favored symbolic icons such as the fish (χθ), anchor, or shepherd. The cross emerged as a revered Christian symbol only after the 3rd–4th centuries, particularly in the Middle Ages, when fragments of the so-called "True Cross" were distributed widely. Archaeological, physical, and cultural evidence, however, shows that these relics cannot plausibly originate from the original wood of Jesus' crucifixion. The paper concludes that the True Cross relics are cultural-religious constructs of the medieval church rather than authentic 1st-century artifacts

It is unknown how many relics there are of the True Cross, reputedly the wood of the cross on which Jesus was crucified. Many churches around the world claim to have a fragment or fragments of the True Cross, which are held in reliquaries. The prevalence of these claims led John Calvin to argue that all the extant fragments of the True Cross, if put together, would fill a large ship. However, in the 19th century French architect Charles Rohault de Fleury made an inventory of all the alleged relics of the True Cross and found that, if put together, they would not constitute enough wood to crucify a man.
