Preslav and Ohrid · Main period: First Tsardom
The disciples bring the books
How do the disciples continue Cyril’s work?
The disciples of Cyril and Methodius arrive at Boris I’s court. In Pliska, Preslav and Ohrid, their translations find teachers and copyists. Two stone inscriptions reveal the different forms of Glagolitic and Cyrillic.

Part 1 · Main period: First Tsardom
Cyril creates Glagolitic
Cyril, earlier known as Constantine, and his brother Methodius came from Thessalonica. Around 863, they went to Great Moravia, a state in Central Europe. Prince Rastislav had requested teachers who could explain Christianity in a language people understood.
Cyril created Glagolitic, the first Slavonic alphabet. The brothers used it to write translations of church texts from Greek. The books’ language is called Old Bulgarian or Old Church Slavonic. It differs from Bulgarian spoken today.

Part 2 · Main period: First Tsardom
A welcome in Pliska
Cyril died in Rome in 869, and Methodius in 885. After Methodius’s death, some disciples were imprisoned and expelled. Clement, Naum and Angelarius reached Bulgaria. According to the Institute for Bulgarian Language, Boris I welcomed them in Pliska in 886.
Boris supported their work. Worship, the shared prayer in church, needed books. It also needed people who could read and teach. This support probably helped their work continue.

Part 3 · Main period: First Tsardom
Glagolitic in stone
Look at the signs below the carved foliage. This is the Baška Tablet, from about 1100, from present-day Croatia. It shows the later use of Glagolitic. The disciples did not bring this tablet to Bulgaria. Its text mentions a gift of land by King Zvonimir.
Some letters have loops; others resemble crosses. The original is kept in Zagreb; the church in Jurandvor has a replica, meaning a copy. The script is mainly Glagolitic, although it includes other signs.
- 1 · A cross-shaped sign
- A cross-shaped sign appears at the start of the upper line. Look at the crossing strokes. The beginning has different scholarly readings; here we observe its shape without insisting on one reading.
- 2 · A letter with loops
- Here in the second line is a sign with two rounded parts. Compare it with the cross-shaped form. Glagolitic letters did not keep identical shapes throughout the centuries.

Part 4 · Main period: First Tsardom
Activity: the first alphabet
Which alphabet did Cyril create for Slavonic speech?
Why is that?
The first Slavonic alphabet was Glagolitic. The name Cyrillic does not make it the same alphabet.
Correct · Glagolitic

Part 5 · Main period: First Tsardom
Clement and Naum teach
Clement taught in the southwestern lands of the Bulgarian state, associated with Ohrid. In 893, he became a bishop, who leads a church community. Naum took over teaching.
In the northeast, people worked with books around Pliska and Preslav. We call these centres literary schools: people translated, wrote and taught others in monasteries and churches. Both regions used Glagolitic books. Research indicates that Glagolitic was used in Preslav too.

Part 6 · Main period: First Tsardom
Activity: put events in order
Put the events in order, from earliest to latest.
Why is that?
The mission preceded Methodius’s death. The expulsion and welcome in Bulgaria followed. Naum’s teaching after Clement came later.
Correct order
- The brothers leave for Moravia
- Methodius dies
- Boris welcomes the disciples
- Naum takes over teaching

Part 7 · Main period: First Tsardom
Letters on Samuil’s stone
Look at Samuil’s inscription, found in the village of German near Lake Prespa. It commemorates his parents and brother. Its date corresponds to 992–993; often only 993 is given.
The letters are Cyrillic. Cyrillic appeared in Bulgaria around 900. Many signs follow Greek capitals; others represent Slavonic sounds. Researchers suggest that writers in Preslav created it with support from the ruler Simeon. The name honours Cyril, but his alphabet was Glagolitic.
- 1 · A at the start of the line
- At the start of the third line of text is an A. Compare it with the cross-shaped sign on the other tablet. The two scripts use different letter forms.
- 2 · Letters in a name
- The point marks M in Samuil’s name. Its shape is closer to familiar modern capitals. Parts of the text are missing. Damaged passages require comparison with other sources, rather than freely adding missing words.

Part 8 · Main period: First Tsardom
The copyist writes on skin
The photograph shows a page from the Codex Suprasliensis, a Cyrillic book from eastern Bulgaria. It is written on parchment, prepared animal skin. The book is about a thousand years old. Its parts are now in Warsaw, Ljubljana and Saint Petersburg.
Cyrillic and Glagolitic were used alongside each other. Books from the Bulgarian centres spread and were copied in other Slavonic lands. Support for teachers and copyists probably helped books reach more people.

Part 9 · Main period: First Tsardom
Activity: match the roles
Match each person to their role in the story.
Why is that?
These are different roles in work carried on by successive people. Naming Cyrillic in Cyril’s honour does not prove its authorship.
