Midsummer, by contrast, has fewer religious stories attached to it. There are a number of Central European stories which associate this time of year with healing ceremonies linked to water ~ be that rivers, lakes or the morning dew. It is also a time when various fairy troops ride abroad and can, if treated with proper respect, impart blessings to those lucky enough to encounter them.
Goidelic mythology has one battle that takes place at midsummer, beyond that the only other mentions are really connected to Manannan mac Lir the son of the sea (that water symbolism again) who's tribute must be paid by the people of the Isle of Man carrying bundles of meadow grass and reeds up to high places (possibly to form bonfires), a practice said to have continued into Victorian times according to Sophia Morrison's folklore collection. The fairy queen Aine (sometimes described as Manannan's wife and other times daughter) was reputed to live atop Cnoc Aine in Limerick and help the villagers roundabout during the Famine. She was honoured at the feast of midsummer.
If an author were to do for midsummer what Dickens did for midwinter, and create a tale that captured its strands, weaving them into a contemporary yet magical setting ~ what would it be like?
