Archaeologists have discovered a jar that they believe was once used to place a deadly curse on 55 people. The jar is exstimated to be around 2,300 years old, and it was unearthed beneath a commercial building in the Agora of Athens.The magic jar had a large iron nail through it and this led researchers to believe that its sole purpose was to deliver a deadly curse upon its targeted victims."The pot contained the dismembered head and lower limbs of a young chicken," wrote Jessica Lamont of Yale University."All exterior surfaces of the jar were originally covered with text; it once carried over 55 inscribed names, dozens of which now survive only as scattered, floating letters or faint stylus strokes."It is unclear as to who these named individuals were or what they had done wrong to get on the wrong side of the individual placing the curse.
