Glagoljica or Glagolitsa in English, is the oldest known Slavic alphabet created in 9th century by Saint Cyril, a Byzantine monk from Thessaloniki, (Greece today). Cyril and his brother Methodis were sent by Byzantine Emperor Micheal III to Great Moravia to introduce the civilization with the Christianity. They found that most of the people spoke Old Slavic that was very hard to adjust in writing to Latin or Greek alphabets.Cyril decided to create a new alphabet, Glagolitic, that was used in Moravia spreading to the west and south by Cyril’s students. Although by 12th century the alphabet ceased of use in other Slavic countries, Croatia preserved the alphabet and used it until the 20th century. The Glagolitic alphabet can be found all over Croatia, there are even a special round type of the alphabet that was approved by Pope Innocent IV in 13th century and was used in Dalmatia and Adriatic Coast.
You can see Glagolitic writing in Zagreb in a cathedral of St. Stephan. When you walk in the cathedral turn right and look at the back wall, you will see giant writing in some strange letters.
Baska Tablet is one of the oldest monument with Glagolitic inscription. The original is saved in Croatian Academy of Science and Arts in Zagreb. Little stone replicas of tablet are common to find in the Croatian houses hanging on the wall proudly, representing Croatian unique heritage.
