Did Medieval church graffiti just unmask the killers of a 12th-century Russian prince? Andrey I Yuryevich, commonly known as Andrey Bogolyubsky (“Andrew the God-Loving”), was a grandson of Vladimir Monomakh, the Grand Prince of Kiev from 1113 to 1125. He was brutally stabbed to his death in his bedchamber on June 29, 1174. 

Discovery News reports:

Found on the east wall of the Cathedral of the Transfiguration of the Savior in Pereslavl-Zalessky, some 60 miles from Moscow, the inscription names 20 conspirators and briefly describes what happened on the night of June 29, 1174, when Prince Bogolyubsky was stabbed to death in his bedchamber...“We suppose the inscription was some sort of official announcement about the murder of Prince Andrey and the condemnation of the murderers,” Alexey Gippius, professor at the National Research University Higher School of Economics and correspondent member of the Russian Academy of Sciences, told Discovery News. “The number of the names confirms information given by the chronicles, where however only three names are mentioned,” he added.
