A unique artifact from the Khorezmshahs has been discovered in London.

The British Museum houses a unique artifact associated with the name of Jalal ad-Din Manguberdi, the last Khwarezm Shah. This is a carved stone block known as the "Stone of Poison," dated to the years 1230/1231 AD. The museum's catalog number for the exhibit is №1990.06.12.1.

The stone, crafted using carving and engraving techniques, boasts impressive dimensions: 29 cm in height, 50 cm in width, and 32 cm in thickness. The weight of the artifact is 42.5 kg. It is categorized as an architectural object of Islamic culture.

According to information from the British Museum, the stone narrates the military campaigns of Jalal ad-Din Manguberdi during the final years of his life. The geographic scope of these campaigns included eastern Turkey, northwestern Iran, and Azerbaijan. The stone was discovered in Iran and was later acquired by the museum at an auction.

It is noteworthy that the mention of the "stone of poison" (jada) appears in the historical work "The History of the Four Uluses" by Mirza Ulugh Beg. The author indicates that Turkic peoples used similar stones for divination and as talismans against evil forces.

Further study of the "Stone of Poison" may illuminate historical events of the Khwarezm Shahs era and reveal new details about the cultural traditions of that time. Experts continue to investigate this valuable artifact.
