The saint made of tiles

Why is this face made of tiles?

9 scenes · 6 min · Sources · 15

In 1909, broken painted clay tiles came out of the ground near Preslav. Pieced together, they formed the image of St Theodore. According to the Metropolitan Museum of Art’s 1997 catalogue, no other surviving painted-tile image approaches it in size. The story runs from the conversion and the new capital to the workshops where clay became an icon.

Part 1 · First Tsardom

A face in a hundred pieces

In 1909 Yordan Gospodinov, a schoolteacher from Preslav, began digging at a place called Patleina, south of the walls of the old capital. In the rooms around a small church he found tiles of fine white clay, painted and glazed. Some carried letters. Slowly the pieces came together into a face: a man with a long pointed beard, large eyes and a round halo. Greek letters survive on three other tiles, from which the name Saint Theodore is reconstructed. The 1997 catalogue describes the icon as assembled from about a hundred fragments. It is kept at the National Archaeological Institute with Museum of the Bulgarian Academy of Sciences in Sofia. Why was the saint painted on separate tiles? And do we know who the painter was?

Part 2 · First Tsardom

The new capital

The Metropolitan Museum of Art’s 1997 catalogue dates the icon to the late 9th or early 10th century; the National Archaeological Institute with Museum presents it as a 10th-century work. Prince Boris I accepted Christianity from Constantinople around 864. Sources and historians give years between 864 and 866, and converting the whole population probably took several years. The capital at the time was Pliska. In 893 Boris's son Simeon came to the throne and the ruler's seat moved to Preslav. The town was not new: earlier structures were found beneath the buildings of the capital period; researchers tentatively date them to the first quarter of the 9th century. Under Simeon and his son Peter, Preslav filled with palaces, churches and monasteries. One of them stood at Patleina, about two kilometres south of the fortress wall.

The saint up close

The 1997 catalogue describes twenty-one painted tiles and three more with the name, with the assembled image about 55 centimetres high. The tiles are approximately 12 by 12 centimetres. The painter worked with a dark brown outline, ochre, brown and a reddish slip, then added a transparent and a dark violet glaze. The old reproduction shows an incompletely preserved image. During conservation in 2014–2015, earlier conservation materials were removed and the original fragments were mounted on a new support. Tap the points to look at the details.

1 · The gaze
Large almond-shaped eyes and a slight asymmetry of brows and nose give the face a focused, almost frowning look.
2 · The halo
The circle around the head is a halo, a sign of holiness. The museum describes it as ochre yellow; colours in this old photograph may differ from the original.
3 · Tile edges
The straight lines are the edges of square tiles, about 12 cm each. The irregular cracks are breaks; the 1997 catalogue describes about a hundred fragments.
4 · Lines in threes
A dark mantle is draped over an ochre tunic. The lines painted in groups of three are unexplained: folds in the cloth, or a fringe on the mantle like those worn by ascetic saints.

Clay, water and fire

Patleina was a workshop as well as a monastery. Archaeologists found basins where white clay was washed and left to settle, and kilns for firing. The clay was local and rich in kaolin. Tiles were shaped and fired, then painted, glazed and fired a second time. About a dozen workshops of the 9th and 10th centuries are known around Preslav. One stood right by the Round, or Golden, Church, whose decoration combined carved marble, glass mosaic and painted tiles. Craftsmen made wall facings, cornices, floor inlays and small icons. When the first tiles came to light, many people took them for imports from Byzantium. Excavations showed they were made on the spot.

Letters in clay

The tiles also speak about books and writing. In 886 Boris welcomed Clement, Naum and Angelarius, disciples of Cyril and Methodius who had been driven out of Moravia. With the support of Boris and his successors, centres of Slavic learning developed at Pliska, Preslav and Ohrid. Gradually, Slavic entered worship and literary life. Monks in Preslav translated from Greek and wrote new texts. Some ceramic tiles carry church texts in Cyrillic. Cyrillic is linked to the work of the disciples of Cyril and Methodius in Bulgaria towards the end of the 9th and the start of the 10th century; it is based on Greek capital letters. Who exactly put it together, and in which centre, is still debated. The name of Saint Theodore on our icon, though, is reconstructed from a Greek inscription.

Which Theodore

During the Middle Byzantine period, two military saints named Theodore were venerated: Tiron and Stratelates. Both were usually depicted armed. In the surviving part, our saint wears a mantle and carries no weapon, so scholars disagree about which of the two he is. One suggestion is that the painter followed an older model from a time when only one Theodore was venerated and shown in civilian dress. The origin of the technique is also debated: Constantinople, the art of the East, or a local Preslav tradition. The 1997 catalogue of the Metropolitan Museum of Art calls the icon the oldest surviving monumental icon of the newly converted state. Preslav remained the capital for about eighty years. In 971 the Byzantine army captured Preslav. According to archaeologist Katya Melamed, the Patleina monastery was also destroyed then; she links the end of Preslav painted ceramics to the city’s decline in the late 10th century.

Boris accepted Christianity around 864; in an interview for Bulgarian National Radio, historian Hristo Matanov also discusses the dates 864/865 and 866. The disciples were received in 886, Simeon took the throne in 893, Preslav fell in 971, and the icon was found in 1909.
