Bust of Constantine Found in Rome Sewer

Archaeologists found the 60cm (2ft) head while clearing an ancient drainage system in the ruins of the Roman Forum.
Eugenio La Rocca, superintendent of Rome's artefacts, described the head as a rare find and said it was possible it had been used to clear a blocked sewer.
Constantine, who reigned from 306 to 337, is known for ending persecution of Christians and founding Constantinople.
Although most of his subjects remained pagans, he is credited with helping to establish Europe's Christian roots by proclaiming religious freedom.
