The Thesmophoria festival was dedicated to goddess Demeter and her daughter Persephone. Only women, particularly married women,
were allowed to take part in the festival, including their children in case they were still little.
The Thesmophoria festival was celebrated throughout Greece and lasted three days, starting with a procession, continuing with a fasting day, and ending with the "Kalligenia", where the women, dressed in snow-white clothes, were enjoying themselves. Other characteristic parts of the celebration was the sacrifice of a boar as well as the peculiar exchange of obscene jokes that used to make goddess Demeter laugh.
