Friday 24th June is Midsummers Day and was considered magical in Cornwall and Ireland, when there was feasting, fires, songs, and dances. Bonfires were kindled on high hills to commemorate the high point of the year.
Traditionally, the veil is thin between the dimensions housing the living and the dead at this time, hence its setting for Shakepeare's Play a Midsummer Night's Dream.
June 24th was designated as a feast celebration called St John's Day in the Christian Calendar, dedicated to the marytr St John The Baptist. The observance begins the night before as St John's Eve. It's also commemorated in Freemasonry.
However, Midsummer's Day celebrations long predates Christianity, and has existed under different names and traditions globally.
24th June is also the Roman Festival of Fors Fortuna. Fors is an ancient Roman Goddess of prosperity, good luck, and divine blessings. Her name means "She Who Brings", from the Latin verb fero, synonymous with abundance and success. This seems to have merged with Fortuna, probably originally a Goddess of fertility, into the Goddess called Fors Fortuna, who was acknowledged as sometimes being fickle or wanton and representing Fortune as Goddess of luck or chance.
She was especially worshipped by slaves and commoners, as the Goddess who could bring about rags-to-riches transformations; with at least two dedicated temples in Rome being founded by former slaves in gratitude for their changed luck. It also looks to have been the origin of the phrase Wheel of Fortune.
By keeping traditions, communities in Ancient Britain retained a sense of harmony and connection, thereby bringing balance and wellbeing into their lives.
