Lear (gen.), Lir, is the sea. He is also a mythological personage, a god in the elder Irish belief, and father of Mănănnán, the Erse Neptune.

Afterwards, later ballads humanized Lear, and made him the father of Mănănnán, one of the Tuath De Danan, or early conquerors of Ireland, and Lord of the Isle of Man, which is said to be called after him. There is a tradition in Londonderry that his spirit lives in an enchanted castle in the waves of Magilligan, and that his magic ship appears every seventh year. Moreover, the daughters of Mănănnán, granddaughters of Lear, were called Ainè and Aoiffè, and had a desperate quarrel about their husbands' excellence in hunting.

Wales, on its side, shows in the Isle of Anglesea a cromlech, called the tomb of Bronwen, daughter of King Llyr or Leirus. The tomb was opened in 1813, and an ancient urn, once probably containing ashes, was found there. It seems that a somewhat more substantial Llyr lived about the time of the Roman conquest, and was the father of Bronwen, who married the king of Ireland, was ill-treated by him, and received a box on the ear, which was one of the three fatal insults of the Isle of Britain. This lady is very probably the Bronwen of the cromlech; but the conjecture of the Rev. Edward Davies is, that in the story of King Lear, we may have the remains of an ancient myth.

It is certainly remarkable that the notion of Lyr, in connection with turbulent daughters or granddaughters, should be common to both Britain and Ireland. Mr. Davies explains Cordelia to have been originally Creirdyddlydd, the token of the overflowing, also called Creirwy, or the token of the egg. Creir is a token, the sacred article on which a man makes oath, whence it came to mean either a relic or a jewel. Creirdyddlydd might thus be the jewel of the sea, or the token of the flood. At any rate, Creirdyddlydd or Creirwy is a creation of ancient Welsh poetry, once mythical, the daughter of the sea, Llyr or Llud, on which Geoffrey seized for his history. Bronwen, or white bosom, is either another daughter of Lyr, or else Creirdyddlydd under another name, and is supposed to have been the British Proserpine. Both Bronwen and Creirwy are called Gwrvorwyn, man-maid, or virago, and it does not seem impossible that here we see the origin of Cordelia, Regan, and Goneril, as they have been adapted to English pronunciation, the token of the overflowing, the fair bosom, and the virago. Surely these are the daughters of the ocean, rebellious and peaceful. Dynwen, too, is the white wave, the patroness of lovers; and as we shall find by-and-by wave names are remarkably common among the Welsh.

Lear is also called Llwyd, the grey, or the extended, a fitting title for the sea, and which has passed on to form Lloyd, so common as a Welsh Christian and surname, and adopted in England as Floyd.

Creirdyddlydd has due justice done her in the Mabinogion, where we further learn that she remains with her father till the day of doom, and that in the mean time two kings, Gwyn ab Nudd and Gwythir mab Graidiawn, have a battle for her hand on every May-day.

Cordula is set down in Welsh and German calendars on the 22nd of October as one of the 11,000 virgins, her feast following that of St. Ursula. It may be remembered that St. Ursula was said to be Cornish; and that her only recorded companion should bear a Cymric name, is in favour of some shade of foundation for her story. Kordula is in consequence a German name. Kordula was a princess of Lingen in 1473; and Michel and Kordel are two children in German household tradition so constantly falling into mishaps as to have become a proverb for folly.

The Germans fancy Cordula is a diminutive of the Latin cor, a heart; others have wildly made it the feminine of Cordeleo, lion heart, and it has been confused with Delia, the epithet of Diana, from Delos, her birthplace; but Creirdyddlydd is certainly its origin, and remembering that in Welsh d is softened and aspirated by being doubled, is not far from it in sound. Cordelia is hereditary in some Irish families; but is chiefly used for love of Shakespeare’s heroine of filial love.

Bronwen makes her appearance again in the romance of Sir Tristram, under the name of Brengwain, the maid of Yseulte. When the Lady Yseulte was sent from her home in Ireland, under the escort of Tristram, to be married to King Mark, of Cornwall, her mother entrusted a love potion to Brengwain to be given on the wedding night.

Unfortunately, a tempest arose on the voyage, and, in the consequent exhaustion, “Swete Ysonde, the fre, asked Brengwain a drink.” And Brengwain, bringing the magic cup by mistake, caused the fatal passion between Yseulte and the knight.
