The strange deposits were placed right on top of a home that was destroyed during the 17 A.D. earthquake. The archaeologists think these objects may have been buried to prevent future disasters. Eggs and bronze tools also have a long history of association with curses and protection against evil forces.
There seems to be a long tradition of ritual burials at Sardis. In the 1960s, for example, archaeologists found 30 of these "ritual dinners" or "puppy burials" at Sardis, which date back nearly 500 years before the eggshell offerings were buried.
