Computer technology to be used to read inscription on Roman altar

Two experts from the University of Mainz in Germany are using the latest computer technology to try to decypher the "invisible" inscription on a 3th century Roman altar. The stone was discovered in the River Tyne in 1672, but has never been legible. (video)

Bjorn Brecht and Bruno Kessler will use a specially-designed program to read the altar which is owned by the Arbeia Roman Fort and Museum in South Shields, England. The altar is believed to "commemorate the safe return of the Emperors Caracalla and Geta to Rome after leaving Britain in AD 211."
