The fountain of Anna Perenna was found in 1999 during excavations for an underground car park on the corner of Piazza Euclide and via G. Dal Monte, in the Parioli district north of Rome. The excavation, carried out at a depth of between about 6 and 10 meters above street level, has brought to light the remains of a fountain walled rectangular in shape with inscriptions bearing the name of the goddess. Anna Perenna was an ancient Roman god of beginnings, celebrated on the day of the Ides of March, the primitive Roman New Year, as well as testimoniatoci by Ovid in the Fasti.
The fountain seems to be attested at least the fourth century BC used until the sixth century A.D. In the tank behind the fountain were found in the mud caked various objects used for religious rituals and magical practices: laminette lead with curses, lead containers containing anthropomorphic figurines, a copper kettle and various coins and oil lamps. These and other objects are now preserved in the epigraphical section of the Museo Nazionale Romano at the Baths of Diocletian. The visit to the fountain is introduced by a path which describes the topography of the area in Roman times, which begins at a cave at the foot of the mountains Parioli and continues with the description of the remains of a Roman building preserved in the Auditorium.
The discovery of the magic rituals practiced at the fountain of Anna Perenna with the presence of hermetically sealed containers with real "voodoo dolls" within them, is completely changing the perspective and knowledge on the relationship of the ancient with the magical-religious sphere. The presence of real professional magicians at the fountain in Piazza Euclide provides a new perspective on the relationship between the man and the ancient religiosity
In 2000, investigators have worked with the Archaeological Superintendence of Rome, following the discovery of some lead containers within the source dedicated to the goddess "Anna Perenna." Were found three cylinders, one inside the other closed. The smallest was sealed with the material on which were engraved fingerprint papillary fragments, identified from an examination of the police.
