If Llew is a sun-god, the equivalent of Lug, it is curious that he is never connected with the August festival in Wales which corresponds to Lugnasad in Ireland. There may be some support to the theory which makes him a sun-god in a _Triad_ where he is one of the three _ruddroawc_ who cause a year's sterility wherever they set their feet, though in this Arthur excels them, for he causes seven years' sterility![388] Does this point to the scorching of vegetation by the summer sun? The mythologists have not made use of this incident. On the whole the evidence for Llew as a sun-god is not convincing. The strongest reason for identifying him with Lug rests on the fact that both have uncles who are smiths and have similar names--Govannon and Gavida (Goibniu). Like Amæthon, Govannon, the artificer or smith (_gôf_, "smith"), is mentioned in _Kulhwych_ as one whose help must be gained to wait at the end of the furrows to cleanse the iron of the plough.[389] Here he is brought into connection with the plough, but the myth to which the words refer is lost. A _Taliesin_ poem associates him with Math--"I have been with artificers, with the old Math and with Govannon," and refers to his _Caer_ or castle.[390] Arianrhod, "silver wheel," has a twofold character. She pretends to be a virgin, and disclaims all knowledge of her son Llew, yet she is mistress of Gwydion. In the _Triads_ she appears as one of the three blessed (or white) ladies of Britain.[391] Perhaps these two aspects of her character may point to a divergence between religion and mythology, the cult of a virgin goddess of whom myth told discreditable things. More likely she was an old Earth-goddess, at once a virgin and a fruitful mother, like Artemis, the virgin goddess, yet neither chaste nor fair, or like a Babylonian goddess addressed as at once "mother, wife, and maid." Arianrhod, "beauty famed beyond summer's dawn," is mentioned in a _Taliesin_ poem, and she was later associated with the constellation Corona Borealis.[392] Possibly her real name was forgotten, and that of Arianrhod derived from a place-name, "Caer Arianrhod," associated with her. The interpretation which makes her a dawn goddess, mother of light, Lleu, and darkness, Dylan, is far from obvious.[393] Dylan, after his baptism, rushed into the sea, the nature of which became his. No wave ever broke under him; he swam like a fish; and hence was called Dylan Eil Ton or "son of the wave." Govannon, his uncle, slew him, an incident interpreted as the defeat of darkness, which "hies away to lurk in the sea." Dylan, however, has no dark traits and is described as a blonde. The waves lament his death, and, as they dash against the shore, seek to avenge it. His grave is "where the wave makes a sullen sound," but popular belief identifies him with the waves, and their noise as they press into the Conway is his dying groan. Not only is he _Eil Ton_, "son of the wave," but also _Eil Mor_, "son of the sea."[394] He is thus a
