The famous "Sin-stone" located in the Yaroslavl region on the shore of Lake Pleshcheyevo began to move again.
The blue stone (Blue-stone) is part of a pagan sanctuary near Lake Pleshcheevo, Pereslavl-Zalessky, Alexandrovaya Mountain and the ancient settlement of Kleshchin. This is one of the few genuine ritual objects that have survived from the times of pagan Rus.
The stone got its name from the fact that after rain the color of the stone changes from gray to blue (this color takes on its wet surface). The stone consists of fine-grained quartz biotite schist. The blue color is formed from the refraction and reflection of light by the surface of biotite flakes and quartz grains.
The stone is 0.6 m thick, 3.1 m long, 2.6 m wide. The stone is dotted with small tubercles. According to the latest research, the weight of the stone is about 12 tons.
The blue stone was the object of worship of the Merians, and then of the ancient pagan Slavs who came to the lake in the 9th-11th centuries from the Novgorod and Dnieper lands. The essence and nature of the religious activities carried out at the stone in pre-Christian times are unclear to modern science.
Now the stone is located on the shore of Lake Pleshcheyevo, but before it lay near the Borisoglebsk Nadozerny Monastery, between the old and new water pumps. The life of Irinarch of Rostov clearly indicates that the stone was in a ravine. (According to the idea, rooted in tourist guides, the former place of the stone is the peak of Alexandrov Mountain, which is not true.)
