Both curses feature a depiction of a deity, possibly the Greek goddess Hekate, with serpents coming out of her hair, possibly meant to strike at the victims. Both curses contain Greek invocations similar to examples known to call upon Hekate.
The two curses, mainly written in Latin and inscribed on thin lead tablets, would have been created by two different people late in the life of the Roman Empire. Both tablets were rediscovered in 2009 at the Museo Archeologico Civico di Bologna, in Italy, and were originally acquired by the museum during the late 19th century. Although scholars aren't sure where the tablets originated, after examining and deciphering the curses, they know who victims of the curses were.
One of the curses targets a Roman senator named Fistus and appears to be the only known example of a cursed senator. The other curse targets a veterinarian named Porcello. Ironically, Porcello is the Latin word for pig.
Celia Sánchez Natalías, a doctoral student at the University of Zaragoza, explained that Porcello was probably his real name. "In the world of curse tablets, one of the things that you have to do is to try to identify your victim in a very, very, exact way."
