Inundations, not temporary floods but the permanent flowing of waters across the land; there are many stories of such flowings from springs or wells to make lakes, or rushing to meet the sea to re-shape the coastline. There are recurrent stories behind these legends, superficially of pride, arrogance, presumption, though this might mask a quest for knowledge and therefore power. Often the consequences are delayed and the flood comes after many generations (time for the otherworld deities is not our time). The legend of the drowning of Tyno Helig near the estuary of the River Conwy in North wales is typical of the theme where a wicked ruler is told that his descendants will be punished for his deeds and so he thinks he has nothing to worry about, but seven generations later his lands are flooded during a feast and only the harper escapes drowning. This latter detail of the harper is also a common element in the stories. John Rhŷs thought that the theme of delayed punishment for evil deeds was a later development in these stories which originally involved something happening at a sacred well which causes it to overflow. Consider for instance, the story of Boann who looks into Nechtan’s Well of Wisdom which should only be visited by Nechtan and his cup-bearers. The well overflows and chases her all the way to the sea, thereby forming the River Boyne. In the story of the drowning of Cantre’r Gwaelod, or the lands of Gwyddno Garanhir, Mererid is herself a cup-bearer and a well-maiden, though the oblique nature of the verses which record this (probably originally contained in a prose saga which supplied more detail) means that the context is unclear.
But no matter. For there is more to say. Both the setting for Tyno Helig and that for Cantre’r Gwaelod are also settings for different surviving versions of the story of Taliesin. Think now of that harper who survives (or is re-born from) the flood. The story of Taliesin begins at Llyn Tegid, the location of another inundation legend which explains the formation of the lake near the town of Bala. This is where Gwion stirred Ceridwen’s cauldron. The River Dee (Dyfrdwy) which runs through the lake, has its own mythos naming its waters as sacred (~>). Gwion looked into, and tasted, the waters of this cauldron and there was an inundation. He gained wisdom just as Finn gained wisdom either by tasting the salmon from the Well of Wisdom or, in another story, tasting drops of water from an otherworld well.
In Gaul a god that the Romans called Mercurius – though he may not have had a name before the Romans gave him one – was partnered with Rosmerta, whose name could simply mean ‘The Great Provider’. Rosmerta had a site of devotion at a sacred spring in Gaul and is also commemorated in Bath, the site of the sacred springs of Sulis in Britain. One of her emblems is a bucket (cauldron?) and she is represented with Fortuna on one relief where the bucket could symbolise re-birth. A spring, a cauldron, a brew of otherworld wisdom, welling into our world. A cup-bearer, a well-maiden ~/~ the keeper of the cauldron, a hag. Are these two sides of the same coin, the turning of Fortuna’s wheel? When there is a flow from otherworld streams out of the well or the cauldron, who can catch the essential drops on the tongue, taste the salmon or gather the hazel nuts that have fallen into the the waters of the well?
Think of that harper, the survivor of the flood. Think of Taliesin, re-born from the waters into a weir in which salmon are caught. Think of others whose quest for knowledge transforms them into divine or inspired figures.Then consider that Mercurius, Rosmerta’s partner, may have been known in the lands that overlapped Gaul as Woden, and how a god, taking a different name for a different people, might do things differently, and yet still discover sources of wisdom, of inspiration, and how the mead of poetry from the Cup or Cauldron of Inspiration might be dispensed to the poets, the awenyddion, the drui, from whom the waters of the Cauldron flow as rivers of song.
