Bolorgir
In the 10th century, but especially in the early 13th century, a capital letter would be accompanied by a lower case or bolorgir, which was easier to write and took up less space. Paper became available alongside parchment from the end of the 10th century. It was at this time that the Bible began to be copied into a single compilation. This script was used until the 16th century, and continued to exist until the 19th century. The erkatagir, the first form of writing in the 5th century, was then used as the capital letter for the bolorgir, which remained the main script.
