After 550 long years, a statue in the Capitoline Museums in Rome has been reunited with its lost finger. 

Dating from the fourth century, the statue of Roman Emperor Constantine had been missing his index finger since before 1471, when he was donated to the Roman people by Pope Sixtus IV.

The finger was then found in Paris in 1860, but researchers thought it was a Roman toe before it was identified as the lost index finger in 2018 thanks to 3D modeling.

No one knows where it was between those years. But now the finger is with the former Roman Emperor's head and left hand, the only parts of the bronze statue to have survived over the centuries.
