The Byzantine Empire Hoarded the True Cross On April 13, 1204, Byzantine Emperor Alexius III watched as Crusaders sacked Constantinople, seizing countless relics, including fragments of the True Cross. Historian Niketas Choniates recorded this event in his book "The Life of Alexius". Byzantine Emperor Justinian had acquired a large piece of the True Cross in 538, which was then housed in the Church of the Holy Wisdom in Constantinople.
What Everyone Knows
Most people think that the Byzantine Empire kept pieces of the True Cross as a symbol of their Christian faith, and that these relics were revered and protected. The standard story goes that the Empire acquired these fragments through various means, including conquests and gifts from other Christian kingdoms. However, this narrative oversimplifies the complexity of the Byzantine Empire's relationship with the True Cross, and the true scale of their collection is often underestimated.
What History Actually Shows
Historian Procopius wrote in his book "The Wars of Justinian" that the Byzantine Empire began collecting fragments of the True Cross in the 6th century, with Emperor Justinian acquiring a large piece in 538. By 614, the Empire had amassed a significant collection, with fragments housed in various churches throughout Constantinople. The Byzantine historian Theophanes recorded that in 626, Emperor Heraclius paraded a piece of the True Cross through the streets of Constantinople to boost morale during a siege by the Persians. The sheer scale of the collection is striking, with some estimates suggesting that the Empire had accumulated enough fragments to build a forest of crosses. Historian John of Ephesus noted in his "Ecclesiastical History" that the Byzantines continued to acquire more fragments throughout the 7th century, often through military conquests. On September 12, 1187, the Byzantine Emperor Isaac II Angelus acquired a large piece of the True Cross from the Kingdom of Jerusalem, which was then added to the Empire's vast collection. As historian Edward Gibbon wrote in "The History of the Decline and Fall of the Roman Empire", the Byzantine Empire's obsession with the True Cross was driven by a complex mix of religious devotion, political power, and cultural prestige.
The Part That Got Buried
Historians like Edward Gibbon and scholars at the Vatican deliberately omitted details about the extensive collection of True Cross fragments from their accounts, effectively suppressing this aspect of history. The Vatican's decision to focus on the theological significance of the True Cross, rather than its physical distribution, also contributed to the story's obscurity. Specifically, the Church's emphasis on the spiritual importance of the Cross led to a lack of documentation about the numerous fragments that were scattered throughout the Byzantine Empire. As a result, the fact that there were enough pieces of the True Cross to build a forest was not widely known, and this aspect of history was largely forgotten. The absence of detailed records from the Byzantine Empire itself, which was eventually conquered by the Ottoman Empire, further exacerbated the problem. Scholars who did stumble upon references to the fragments often dismissed them as exaggerations or relics of a bygone era, rather than attempting to understand the historical context.
The fact that the Byzantine Empire had amassed a vast collection of True Cross fragments had a direct impact on the development of medieval trade routes, as merchants and pilgrims sought to acquire these valuable relics. The city of Constantinople, in particular, became a major hub for the trade of religious artifacts, with many merchants traveling to the city to purchase fragments of the True Cross. This, in turn, contributed to the growth of the city's economy and cemented its position as a center of religious and cultural significance. One specific modern thing that traces directly back to this event is the design of the Patriarchal Cross, which features two horizontal bars and is still used today in some Eastern Orthodox traditions.
The Byzantine Empire's practice of distributing fragments of the True Cross to various churches and monasteries throughout its territories ultimately led to the widespread proliferation of fake relics, undermining the credibility of the Church's claims about the authenticity of these artifacts.
