Relics and Pilgrimage in Byzantium
Constantinople held the greatest relic collection in Christendom — the True Cross, the Virgin's robe, the Mandylion. How relics were used, venerated, given as diplomatic gifts, and dispersed in 1204.
By the twelfth century Constantinople held the largest and most valuable collection of Christian relics in the world, and much of the city’s prestige, and a measurable part of its diplomatic leverage, rested on it. Visitors were shown the crown of thorns, the lance, the sponge, the reed, fragments of the True Cross, the robe and girdle of the Virgin, the head of John the Baptist, the mandylion of Edessa, the stone of the tomb, the swaddling clothes, and the relics of several hundred saints.
A Russian pilgrim, Antony of Novgorod, listed what he was shown in 1200 and took two days over it. Four years later most of it was gone.
Why Relics Mattered
The theology is the same as that of the icon: matter can carry holiness because God took flesh, and the honour paid to the object passes to the person. A relic is not a memento; it is a point at which a saint is present and can act.
The practical consequences followed. Relics healed, protected cities, decided battles, confirmed oaths, and legitimised rulers. They were also, unavoidably, property — valuable, portable, divisible, and stealable.
Constantinople’s collection was built deliberately from the fourth century onward. Constantine’s foundation had no apostolic tomb to compare with Rome’s Peter, and the deficiency was made good by importing relics on a large scale: the supposed relics of Andrew, Luke and Timothy to the Church of the Holy Apostles under Constantius II, and a steady accumulation thereafter.
The Great Relics
The True Cross. Found, according to the tradition established by the late fourth century, by Constantine’s mother Helena in Jerusalem. Fragments were distributed across Christendom from early on. The main relic was captured by the Persians in 614 and recovered by Heraclius in 628 — the event commemorated by the feast of the Exaltation of the Cross. Cross relics were the standard high-value Byzantine diplomatic gift, housed in the elaborate staurothekai described in Byzantine enamel and metalwork.
The robe (maphorion) of the Virgin. Acquired in the fifth century and kept at the church of Blachernae. It was the city’s palladium, carried along the walls during sieges — most famously in 626 and again in 860 — and the most important object in the city’s self-understanding.
The mandylion of Edessa. A cloth bearing an image of Christ not made by human hands, brought from Edessa to Constantinople with great ceremony in 944 — an acquisition negotiated as part of a military settlement, which indicates how relics functioned in Byzantine diplomacy. It disappeared in 1204. Its relationship to the later Shroud of Turin has been argued at length and cannot be settled.
The head of John the Baptist, of which there were several, in Constantinople and elsewhere. Multiple claims to the same relic were common and were handled by Byzantine writers with less embarrassment than one might expect.
The Pharos Chapel
The most important relics were kept not in a public church but in the chapel of the Virgin of the Pharos inside the Great Palace — the emperor’s private chapel, functioning as a reliquary treasury.
Access was controlled and was itself an instrument of policy. Foreign envoys were shown the collection as part of the programme of overawing them; a visit to the Pharos chapel was a diplomatic favour. A twelfth-century description by Nicholas Mesarites presents the chapel as a second Sinai and a second Bethlehem, holding the physical remains of the whole Passion.
Pilgrimage
Pilgrims came to Constantinople from Russia, Scandinavia, England, France and Italy, and Byzantine pilgrims went to Jerusalem, Sinai, Ephesus, Thessalonica and the shrines of Asia Minor.
The literature is informative. Russian pilgrim accounts — Antony of Novgorod, Stephen of Novgorod, Ignatius of Smolensk — describe routes, costs and what was shown, and they are among the best sources for the topography of the late Byzantine city. Western accounts do the same from a different angle.
The mechanics resembled modern religious tourism more than one might expect: fixed itineraries, official guides, set fees, souvenirs. The lead and clay ampullae sold at the shrine of St Demetrios in Thessalonica, filled with holy oil, are found across the Balkans and as far as Britain, and they are archaeologically datable, which makes them a map of where pilgrims came from.
Healing shrines operated on the incubation model inherited from the pagan sanctuaries of Asklepios: the sick slept in the church and expected a dream in which the saint prescribed a remedy. Collections of miracle stories from shrines of Saints Kosmas and Damian, Artemios, Thekla and Demetrios record hundreds of these, with details of symptoms, treatments and outcomes that are of genuine interest to the history of medicine.
The Dispersal
The Fourth Crusade in 1204 dispersed the collection across Europe. Relics were taken as plunder, sold to pay debts, and given away.
The most spectacular transaction came later. The Latin emperor Baldwin II, desperate for money, pawned the crown of thorns to Venetian financiers and then sold it, with other Passion relics, to Louis IX of France. Louis built the Sainte-Chapelle in Paris specifically to house them, at a cost several times what the relics themselves had cost.
Hundreds of European church treasuries acquired Constantinopolitan relics in these years, and a genre of self-justifying narrative developed — the translatio, explaining how a relic came west and arguing that the saint had wanted to move. Gunther of Pairis’s account of the abbot Martin filling his robe with relics in a Constantinopolitan church is the most candid and the least edifying.
Afterwards
The restored Byzantine Empire never rebuilt the collection, and by the fifteenth century the city’s remaining relics were being used as security for loans.
The Orthodox world’s relic culture continued elsewhere: on Mount Athos, whose monasteries hold major collections and still display them; in the Russian church; and in the Greek parish churches where a local saint’s relics remain the focus of the annual festival. It is a living practice, not a medieval curiosity, and anyone who attends a panegyri in a Greek village on a patronal feast is watching a continuation of it.
Antony of Novgorod’s Inventory
The single most useful document for the relic collection of Constantinople is a Russian pilgrim’s account written in 1200, four years before the sack, and its value lies in its plainness.
Antony, later archbishop of Novgorod, went through the churches of the city recording what he was shown. He is not writing devotional literature; he is listing, in the manner of a man who has paid for access and intends to remember what he saw.
He records, among a great deal else: in Hagia Sophia, the marble slab on which Christ’s body was prepared for burial, the Passion relics, the well of the Samaritan woman; at Blachernae, the robe of the Virgin; in the Pharos chapel, the crown of thorns, the lance, the sponge, the reed, the swaddling clothes, the sandals; the heads of various apostles and martyrs distributed across a dozen churches; and the bodies of emperors and patriarchs.
He also records practical detail no theological source supplies: which days particular relics were displayed, what the guardians said, and where the objects were kept.
Read against the inventories of European church treasuries compiled after 1204, Antony’s list functions as a “before” photograph. A large proportion of what he saw can be tracked to a specific western destination within a decade of his visit.
Other Russian accounts — Stephen of Novgorod in the 1340s, Ignatius of Smolensk in the 1390s, an anonymous pilgrim of the same period — do the same for the later city and are among the best sources for its topography.
The Ampullae
The mass-produced pilgrim souvenir is the archaeologist’s best evidence for who actually went where, and the Byzantine examples are abundant.
The standard object is a small flask of lead-tin alloy or clay, a few centimetres across, stamped with an image of the shrine’s saint and filled with oil from a lamp burning at the tomb, with water from a holy spring, or with earth from a sacred site.
The largest surviving groups are the Monza and Bobbio collections in Italy — Palestinian flasks of the sixth and seventh centuries, brought back from Jerusalem, stamped with scenes of the Crucifixion, the Resurrection and the Ascension. They are among the earliest evidence for the iconography of these subjects and have been used to reconstruct lost monumental decoration in the Holy Land churches.
The flasks of St Demetrios at Thessalonica are the other major group, and they are found across the Balkans, in central Europe and as far as Britain.
Because the flasks are datable by style and traceable to a single production site, their distribution maps pilgrimage routes directly. A Demetrios ampulla in a seventh-century grave in northern Europe is evidence that somebody made that journey.
The Toll of 1204 in Detail
Following particular objects west makes the dispersal concrete.
| Relic | Destination |
|---|---|
| Crown of Thorns, Passion relics | Sainte-Chapelle, Paris (purchased by Louis IX, 1239–42) |
| The four bronze horses of the Hippodrome | St Mark’s, Venice |
| The Mandylion of Edessa | Vanished; possibly Paris, destroyed 1793 |
| Head of St John the Baptist (one of them) | Amiens Cathedral |
| Body of St Mark the Evangelist (claimed) | Already in Venice since 828 |
| Limburg Staurotheke | Limburg an der Lahn, Germany |
| Relics of St Helena | Hautvillers, France |
| Countless smaller relics | Church treasuries across France, Germany, Italy, Flanders |
The scale generated its own literature. Gunther of Pairis’s Hystoria Constantinopolitana describes his abbot Martin seizing relics in a Constantinopolitan church and filling his robe, and presents it as pious opportunism rather than theft — the saints, on this reasoning, wished to move west.
Pope Innocent III’s own letters condemn the sack in strong terms, which did not prevent the relics from being received and enshrined across Latin Christendom.
