May Day (May 1st) was known since the times of Ancient Rome. On this day the ancient Romans poured water on each other and bathed in the Tiber. At the same time the vestals, the priestesses of the goddess of the family home Vesta, who observed a vow of celibacy, were throwing into the river the reed effigies of Saturn, the god of agriculture. Different European nations celebrated May Day as a day of blooming nature, flowers, and joy.
