The Physician Sons  Nothing is recorded of her husband's anguish at this conclusion to his marriage, but the story goes on to tell how the Lady's sons wandered round by the lake in the hope of seeing their mother again.  One day she did appear to them at a place near Dôl Howell at the mountain gate which is still called Llidiart y Meddygon (Physicians Gate).  She told her eldest son, Rhiwallon, that it was his mission in life to relieve mankind from misery and pain, and gave him a bag full of medical remedies and instructions for their use.  The Lady met her sons on several other occasions after this and showed them where medicinal herbs grew in the area, particularly in Pant y Meddygon (the Physicians Grove), and taught them how to use the medicines thus obtained.  Ground Ivy glechoma lederacca (Eidral) It was in this way that the family became renowned for their medical knowledge and were so well thought of by Rhys Gryg that he endowed Rhiwallon and his two sons with land at Myddfai.  Two farms in the parish are named Llwyn Meredydd Feddyg and Llwyn Ifan Feddyg (Groves of Meredydd and Ifan the Physician), and it is believed that Rhyblid, Ty Newydd and Cwmbran also belonged to the Esgair Llaethdy family.  A survey of 1317 records that a group of free tenants of the manor of Myddfai were to provide the Lord of Llandovery with a doctor, adding credence to the story that there was a tradition of medicine in the parish.  Even today, the horizontal terraces on the north-east facing cliff above Llyn y Fan Fach grow herbs which are found nowhere else in the area, and the place would of course have been known to early physicians like Rhiwallon.   Violet viola (Fioled) Perhaps it was just the proximity of this rich source of medicinal flora which entwined the true story of the Physicians with the local version of the Lady of the Lake story, but the legend has survived over the centuries. During recent years a revival in scientific interest in the medicinal properties of herbs has shown that many of the recipes used by the Physicians of Myddfai would have a beneficial effect on the illnesses for which they were prescribed.
