Note 29 — Chapter I · Undine’s Kymric Sisters (continued 2)

The story, as it proceeds, mentions Trinio engaged in battle with the men of a prince who seems to have been no other than Brychan of Brycheiniog, supposed to have died about the middle of the fifth century. The battle was disastrous to Trinio and his friends, and Trinio was never seen afterwards; so Walter Mapes reports the fact that people believed him to have been rescued by his mother, and that he was with her living still in the lake. Giraldus calls it lacus ille de Brecheniauc magnus et famosus, quem et Clamosum dicunt, ‘that great and famous lake of Brecknock which they also call Clamosus,’ suggested by the Welsh Ỻyn Ỻefni, so called from the river Ỻefni, misinterpreted as if derived from ỻef ‘a cry.’ With this lake he connects the legend, that at the bidding of the rightful Prince of Wales, the birds frequenting it would at once warble and sing. This he asserts to have been proved in the case of Gruffuđ, son of Rhys, though the Normans were at the time masters of his person and of his territory29. After dwelling on the varying colours of the lake he adds the following statement:—Ad hæc etiam totus ædificiis consertus, culturis egregiis, hortis ornatus et pomeriis, ab accolis quandoque conspicitur, ‘Now and then also it is seen by the neighbouring inhabitants to be covered with buildings, and adorned with excellent farming, gardens, and orchards.’ It is remarkable as one of the few lakes in Wales where the remains of a crannog have been discovered, and while Mapes gives it as only two miles round, it is now said to be about five; so it has sometimes30 been regarded as a stockaded island rather than as an instance of pile dwellings.
