it (a feat also attributed to Math son of Mathonwy). The second plague was the scream of two dragons fighting. The third was a giant wizard. The two brothers slew the Corianiad with insects to which ordinary people were immune. The dragons were slain while intoxicated with mead, and the giant was overcome in combat by Lludd.

Llwyd

Llychlyn

Llyn y Fan

[W] A tale in which an a beautiful Otherworld maiden, dwelling in a lake, appears. The hero offers her bread but she disappears; on her second appearance he offers her dough. On the third appearance, when he offers half-baked bread, the gulf between their two worlds is bridged. But she warns the mortal that if he strikes her three careless blows he will lose her straightaway forever.

They lived at Esgair Llaethy, six miles from the lake out of which she came. They had three sons and a prosperous farm with good livestock. Of course, eventually the husband strikes the three careless blows and she gathers up all the livestock and disappears into the moonlit lake. However, she leaves behind her three sons, and when they grow she appears to them and hands them a satchel of medical recipes and prescriptions, so the three bothers become known as Meddygon Meddfai, the most skilled physicians in all Wales. The story has an echo of the Irish tale of Ó Laoidhigh (O’Lee), in which a book full of medical recipes and prescriptions was brought from Hy-Breasal. On finding it Ó Laoidhigh read it and became the greatest physician in Ireland. The Book of the O’Lees (Royal Irish Academy) was written in 1443, partly in Latin and partly in Irish. The pages of writing form patterns resembling astrological symbols. It is a complete system of medicine, treating everything from wounds to hydrophobia.
