Mythological roots
There have been quite a few attempts to provide mythological explanations for the rise of April Fool's Day. One story dates back to Roman mythology, particularly the myth of Ceres (the Goddess of grain and the harvest) and Proserpina. In Roman mythology Pluto, the God of the Dead, abducted Proserpina and brought her to live with him in the underworld. Proserpina called out to her mother Ceres for help, but Ceres, who could only hear the echo of her daughter's voice, searched in vain for Proserpina. The fruitless search of Ceres for her daughter was commemmorated during the Roman festival of Cerealia and believed by some to have been the mythological antecedent of the fool's errands popular on April 1st.
British folklore linked April Fool's Day to the town of Gotham. According to the legend, it was traditional in the 13th century for any road that the King travelled over to become public property. People in Gotham didn't want to lose their main road and spread a false story to stop the King. A messenger was sent to Gotham after King John learned the people's trick. But when the messenger arrived in Gotham he found the town was full of lunatics who were engaged in foolish activities such as drowning fish or attempting to cage birds in roofless fences. The King fell for the hoax and declared the town too foolish to warrant punishment. And ever since then, April Fool's Day has supposedly commemmorated their trickery.
