Officials at Glasgow Museums say a sculpture by world-famous artist Auguste Rodin has gone missing, worth $3.7 million. The museum purchased the plaster version of Les Bourgeois de Calais back in 1901.

Jérôme le Blay, the museum’s director, has regretted the disappearance of the statue but has insisted that it “must be put into the context of the times.”

The Guardian reported that the missing sculpture had sustained damages at the time of the 1949 open-air exhibition.
