The spread of literacy evidences the high level of cultural development in Biarescie. Biarescie citizens learned how to read and write the Cyrillic script – an ancient Slavic alphabet that consisted of 43 letters.
One of the unique finds in Biarescie is a boxwood comb with carved letters of the Cyrillic alphabet on both sides. There are 6 letters on one side and 7 on the other. These letters were carved no later than the beginning of the XIII century, as evidenced by the nature of their marking. This comb is the oldest "literacy textbook" in the territory of Belarus.
