Polish scientist Nicholas Copernicus revolutionized astronomy by introducing the heliocentric world system in which the Earth and all the planets revolve around the Sun. However, since the lifetime portrait of the famous astronomer and mathematician has not been preserved, it is not known exactly what he looked like.

The surviving portrait of Copernicus was painted in 1580, after the scientist’s death in 1543.

Now Brazilian researcher and 3D designer Cicero Morais (Cicero Moraes), who has long been engaged in reconstructing the appearance of ancient and medieval people.

Morais used a skull believed to be that of Copernicus, found in Poland 19 years ago. The skull’s lower jaw was missing, so the reconstructionist used a database of people living today with similar skull parameters. The resulting face looks very similar to Copernicus’ portrait from 1580.
