Through all the archaeology classes I have taken and articles I have read, I have learned that there is always something more at archaeological excavation sites. Whether it’s a new artifact that leads to a new interpretation or new questions or more to a site than was discovered before. In a previous class I had done a project on a port in Italy that was very important during to the Romans called Ostia. While surveying critical ports to Rome during the Romans height, archaeologists have discovered a new boundary wall meaning it was much bigger than they previously thought it to be. Through the use of “geophysical survey techniques”, specifically magnetometry, archaeologists found the boundary wall extended more down the Tiber river and included towers and three more warehouses which were much bigger than previously excavated warehouses. One of which being as big as a football field. This discovery pushes further evidence of commercial activities during the beginning centuries of this ports building. “Director of the Portus Project, Professor Simon Keay says, “Our research not only increases the known area of the ancient city, but it also shows that the Tiber bisected Ostia, rather than defining its northern side.” The Portus Project is working on the important ports of Rome between the 1st through 6th century including the port of Ostia and Portus, Ostia’s neighboring port. Another building was also discovered but its use is still unknown, which is why I believe it’s important for archaeologists to revisit sites that have already had research done on it and for archaeologists to extensively excavate newly discovered sites as to retain as much information from that site as possible. This way archaeologists can get a better interpretation of sites. Professor Keay states, “Our results are of major importance for our understanding of Roman Ostia and the discoveries will lead to a major re-think of the topography of one of the iconic Roman cities in the Mediterranean.” The workings of this project supports that going back to iconic sites like the Roman port of Ostia can give new insights and a better understanding on topics like topography of critical archaeological sites. With the advancement of technology over the last 50 years, archaeologists should revisit sites and use new technology like GIS to bring forward more information and better understandings of the important sites of past civilizations, like the Portus Project did for the Roman port of Ostia.
