Głagolicy

Glagolitic is a Unicode block containing the characters invented by Saint Cyril for translating scripture into Slavonic. The Glagolitic script is the precursor of Cyrylicy  0400–04FF . The Glagolitic alphabet /ˌɡlæɡɵˈlɪtɨk/, also known as Glagolitsa, is the oldest known Slavic alphabet, from the 9th century.

Glagolitic is one of the Slavic alphabets. It's believed that Glagolitic was created by the Slavic enlightener and philosopher Saint Cyril for writing church texts in the Old Church Slavonic language. The literary work about Cyril's life emphasizes that the Slavic alphabet was essential for conveying God's service. Therefore, all church books were also translated into Old Church Slavonic.

A lot of factors and evidence suggest that the Glagolitic alphabet was created much before the Cyrillic. Consequently, Cyrillic was based on the Glagolitic and the Greek alphabet. The oldest inscription, which was made in a Bulgarian church and survived throughout times, refers exactly to 893. In addition, the oldest manuscripts, dated back to the X century, were written in a more archaic language, which was phonetically close to the language of the Southern Slavs.

Do you really need to learn these letters to speak Russian? Of course not. They are for the lovers of Russian history and culture, who are fond of reading old books and documents. For example, students of Russian philology tend to have the subject, which requires studying Old Church Slavonic in order to understand the modern language better. Even professionals don't learn it perfectly. Therefore, you can relax. But if you want to impress your friends, you can copy these symbols and send or post them on social media.
