English fisherman found mysterious sacred cubes from India in the river

The history of plundering by the former British Empire of its Asian colonies has sometimes very unusual consequences. The other day in central England, on the banks of the Sow River near Coventry, a local resident Will Reed, while fishing, found a pile of strange cubes in shallow water. They are made of lead and are lined with incomprehensible symbols, which suggests the religious purpose of the objects.

Through an open survey on the Internet, it was found out that the symbols are Hindu. Probably, the cubes were brought from India to England, but due to the lack of practical use they were thrown away. This is the main mystery - so far no one has managed to figure out the purpose of these unusual objects.

The symbols on the edges are repeated, which makes the pattern resemble Sudoku, since each column, row and diagonal gives a single meaning. This suggests that the cubes are "yantras" - magical tools for focusing attention and performing various rituals in Hinduism. The material of the cubes, lead, in Hindu astrology is a symbol of Rahu, one of the parts of the moon's orbit. Thus, these can be Rahu yantras, that is, a religious set.

Together with the cubes, a coin was found, which depicts a multi-armed woman riding a lion. This is a sign of Durgu, the mother goddess, so it is possible that the cubes were intended for prayers addressed to her. While enthusiasts speculate, scientists are trying to determine the age of the cubes. The latest voltammetric method in the case of lead gives an error of 150 years, which may not matter if we are talking about several millennia. But what if the cubes were made relatively recently?
