The Roman’s dedicated the month of Venus. Veneralia was the first day of the month in the Roman calendar. The first day of her month was a day of celebration and games when the Roman’s tasted the first fruits of spring.
Men would wear women’s clothing, women would remove their jewels and adornments. All would jump into the men’s pools together and….frolic. It was a fine day to wear masks, play tricks and just get a good case of spring fever.
Throughout time, this evolved into a day April Fools Day. Frankly, I think the Romans had more fun!
