These two saints are paid tribute in one of the sides of the Stone Bridge (Kamen Most) located next to the neighborhood of Carsija. Cyril (or Constantine, 827-869) and Methodius (815-885) were two brothers from Thessaloniki during the Byzantine Empire. The two Slavic Apostles became the first Christian missionaries in the Crimea Empire of Great Moravia. They are considered expanders and inventors of the Glagolitic alphabet. This alphabet was used in Slavic manuscripts before the development of the Cyrillic alphabet (which was derived from the Greek alphabet with elements of Coptic and Hebrew alphabets), so therefore used in various Slavic languages.
