I have always been fascinated by ancient curses. We tend to find them on funerary stele or on little bronze tablets in temples. Occasionally, they may be found also in other materials, such as the cup (skyphos) that was unearthed in Methone of Pieria. This is definitely the oldest curse inscribed on a symposium cup and is dated between 730-690 BC. The inscription says ‘I am (the cup) of Akesandros and (whoever steals me) will lose his eyes (or money). It is worth mentioning that another cup with a similar inscription has been found in Kyme, Southern Italy. It looks like some men were very attached to their drinking habits and associated tools!
