Monday 24th June is Midsummers Eve 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.
This 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.
