The Russian Tsar died in 1584. The face of 'Ivan the Terrible', Russia's cruellest tyrant, has been reconstructed by scientists 440 years after his death. The Russian Tsar, who died in 1584, was just three years old when he rose to power and was in his thirties when he gradually deteriorated into a state of paranoia, ordering the brutal execution of anyone he perceived to be a traitor.

According to the New York Post , the terror-loving tsar also killed his son and only viable heir Ivan IV in a fit of fury. Now, Cicero Moraes, a Brazilian graphics expert, used a combination of cutting-edge techniques to create a scientific reconstruction of Ivan The Terrible's face. "It was a very interesting experience as it involved not only facial approximation, but the study of his story," Mr Moraes said in a YouTube video.

Take a look below: According to the Post , Mr Moraes first amassed data from a scientific excavation of the dictator's grave by Soviet researcher Mikhail Gerasimov. "According to Dr Gerasimov's study, it appears that Ivan indulged in a disorderly life of excessive eating and alcohol abuse," he said. "This must have worsened his condition in his last years.

" He added, "An interesting fact is that they found a large amount of mercury in his body, which made some suspect poisoning. But given the habits of the time, it may have been used as a treatment for some health problem." Mr Moraes revealed that the final reconstruction was developed using a combination of scientific .
