In 2015 I wrote about the Hasanlu lovers (left), two skeletons discovered at the site of an ancient Iranian city that had been sacked in the ninth century B.C.

In 2007 archaeologists discovered a similar pair at a Neolithic tomb near Mantua, Italy. It appears the two were no older than 20 when they died; though weapons were found in the grave, there was no evidence that the pair had died violently. Double burials were unusual in that period, but the reason for this one is unknown.

The skeletons are on display in the National Archaeological Museum of Mantua. Archaeologist Elena Menotti, who led the excavation, told Reuters, “We want to keep them just as they have been all this time — together.”
