In the paper an approach to recognition of old Slavonic symbols is proposed, which includes the stages of ternary segmentation, detecting edges of areas, synthesis of two skeleton variants, forming a fuzzy graph, creating a logical description in a fuzzy description logic, and recognition with help of a subsystem of formal automatic reasoning. Results of preliminary experiments are provided, which confirm the perspective of the proposed approach.
