In the Middle Ages, all international contracts, rulers' decrees, and state and private correspondence were stamped by seals hanging on a piece of string. They were made of different kinds of material: "hrisovuls” " - made of gold, "argirovuls " - made of silver, "molivdovuls” " - made of lead, and "kerovuls  " - made of wax.

Ňhe Preslavian collection of medieval Byzantine seals (971-1088) is the world's largest collection discovered in situ ,  during excavations in the administrative building of the palace center. There were more than 500 molivdovuls  found, as well as more than 200 lead cores and moulds. This shows that the place was probably an administrative center (Strategy ), which served the representative of the central Byzantine government after Byzantium conquered Preslav in 972.

In addition, the collection includes the seals of Bulgarian and Byzantine rulers and dignitaries. The seals were found both in the Inner and Outer Towns of Preslav, as well as in its nearby and distant surroundings. They prove that the regular correspondence between Bulgarian and Byzantine courts occurred not only during the period when Preslav was capital, but also before 893. This was the period when Preslav played an important role in both military and administrative structure of Bulgaria.

 

Moulds for casting seals from the Strategy in Preslav.

 

Ňhe metal cores for preparing the seals were preliminary cast in ceramic or stone moulds with circles carved in them. When casting the seal, a cordhole was made through its core, so that the cord could circle round the rolled document or scroll. The final stage of making the seal was to form mould it with a special pair of pliers called "bulotirion " Special matrices were fastened on the sides of the pliers with signs and images engraved in negative relief.

The seal of George Charnets and Bulgarian Sinkel  - a wax seal from the last quarter of the 9th century

 

 It was found in the vicinity of Selishte (The Settlement).

Sinkel was a high-ranking clergyman - the archbishop’s first assistant. It is highly probable that the owner of the seal and Archbishop George, who became the head of the Bulgarian church at the end of 9th century, were the same personality. The two copies of the molivdovul (the other is in the collection of the National Archeological Museum in Sofia) are the first and earliest memorials written in the Cyrillic alphabet.

The seal of Tsar Simeon (913-927) - lead

 

The seal was found near a village called Cherencha in the region of Shumen. Other examples from the same set of seals belonging to Simeon have not been found thus far. The circular sign saying “Simeon the Basileus” suggests that the molivdovul  dates to some time after the coronation of Simeon as Tsar of Bulgaria in Constantinople in 913.

The seal of Teofan - patrician and protovestiaurius (927-934) - lead

 

Location - the Strategy in Preslav

Protovestiarius was a dignitary in the palace of the Byzantine Emperor. He managed the emperor's personal wardrobe and assisted him everywhere even in his military campaigns. Ňhe protovestiarius was also responsible for the personal tasks and work of separate individuals of the emperor’s family. According to historical resources, Teofan had the leading role in settling the marriage between the Bulgarian tsar - Petar and the Byzantine princess - Maria-Irina (the granddaughter of Emperor Romanus I Lakapenos). This fact explains why seals of his own set were found in Preslav.

The seal of Byzantine Emperor Constantine VII (945) - lead.

 

Location - in the vicinity of “Pod Zabuite” ("Under the Teeth" The 'teeth' are the hill that protects and forms the Southwestern boundaries of Preslav)- near the Emperor’s palace.

Judging from the fact that Constantine VII was presented alone, we might assume that the molivdovul dates to 945, the year when the Lakapene dynasty was removed from the throne. All the mail from the Emperor, received in Preslav, probably detailed these changes in the Byzantine government.

Bronze matrix of Tsar Petar - duplicate (? - 969)

 

Location - it was discovered during excavations of the Big Palace in Pliska

The matrix was meant for printing on soft materials (wax, clay). The inscription was written in Cyrillic on both sides of the image. This is the earliest notation in which we see the Bulgarian equivalent of the Byzantine title - basileus that is tsar or caesar.

The seal of Alexius Komnin - sebast and great domestic (1079 - 1081) - lead

 

Location - the Strategy in Preslav

The title “domestic” means a higher-ranking officer in the Emperor’s army. The seal belonged to the future Byzantine Emperor Alexios I Komnenos (1081-1118). In 1079 he was honored with the title “sebast”, which was reserved for the emperor’s family only, as well as for their close associates.

Basil the Head - “spataroipat” (1060s - 1070s of 11th c.) - lead

 

Location - the Strategy in Preslav

Some of the seals make it easier to track down the carrier of their owners. The same is the case with the 5 molivdovuls of Basil the Head. Judging from them, we might assume that he first was a spataroipat (a rank lower than patrician) and a few years later he reached the rank of vestarh, which was second in rank for eunuchs. The duties of the vestarh mainly consisted of managing the personal wardrobe of the emperor - he took care of the official garments, crown, and jewelry.

The seal of vestarh Theodore Dobromir (third quarter of 11th c.) - lead

Location - the Strategy in Preslav

Theodore Dobromir’s carrier could also be tracked according several of his molivdovuls.

The curious thing about this Byzantine dignitary, however, is his Slavic origin, which is obvious from his surname. This proves to be one of the numerous illustrations for the political nature of the  Byzantine administration.
