been an animal god, then an anthropomorphic deity associated with animals. Thus in the _Mabinogi_, when Gwydion flees with the swine, he rests each night at a place one of the syllables of which is _Moch_, "swine"--an ætiological myth explaining why places which were once sites of the cult of a swine-god, afterwards worshipped as Gwydion, were so called. Gwydion has also a tricky, fraudulent character in the _Mabinogi_, and although "in his life there was counsel," yet he had a "vicious muse."[375] It is also implied that he is lover of his sister Arianrhod and father of Dylan and Llew--the mythic reflections of a time when such unions, perhaps only in royal houses, were permissible. Instances occur in Irish tales, and Arthur was also his sister's lover.[376] In later belief Gwydion was associated with the stars; and the Milky Way was called Caer Gwydion. Across it he had chased the faithless Blodeuwedd.[377] Professor Rh[^y]s equates him with Odinn, and regards both as representing an older Celto-Teutonic hero, though many of the alleged similarities in their respective mythologies are not too obvious.[378] Amæthon the good is described in _Kulhwych_ as the only husbandman who could till or dress a certain piece of land, though Kulhwych will not be able to force him or to make him follow him.[379] This, together with the name Amæthon, from Cymric _amæth_, "labourer" or "ploughman," throws some light on his functions.[380] He was a god associated with agriculture, either as one who made waste places fruitful, or possibly as an anthropomorphic corn divinity. But elsewhere his taking a roebuck and a whelp, and in a _Triad_, a lapwing from Arawn, king of Annwfn, led to the battle of Godeu, in which he fought Arawn, aided by Gwydion, who vanquished one of Arawn's warriors, Bran, by discovering his name.[381] Amæthon, who brings useful animals from the gods' land, plays the same part as Gwydion, bringer of the swine. The dog and deer are frequent representatives of the corn-spirit, of which Amæthon may have been an anthropomorphic form, or they, with the lapwing, may have been earlier worshipful animals, associated with Amæthon as his symbols, while later myth told how he had procured them from Annwfn.
