Scientists have proved that the famous skeletons discovered in Modena (northern Italy) belonged to a pair of men. Those human remains are unique because of the fact that those belonged to people holding each other by hand.

When the discovery was made in 2009, scientists were unable to assess the sex of the deceased due to poorly preserved remains. However, thanks to the latest technology – the study of protein on tooth enamel – it was possible to reveal sex.

As it turns out, men lived in the 4th-6th century CE and they were intentionally buried, holding by hand. Researchers speculate that they could have been twins, cousins or soldiers who were killed in battle.
