=== スコットランドの民間伝承 ===
スコットランドの民間伝承では、オェングスは冬を支配するベイラ(カリアッハベーラ、Cailleach)の最も美しい息子とされている。オェングスは冬の間ティル・ナ・ノグに滞在していたが、ブリギッドの夢を見たことから、彼女を探すためにこの地を訪れるようになった。ブリギッドは、その美しさを妬んだ妖精の女王に監禁され、無理な雑用を押し付けられていた。オェングスはブリギッドを探すため、8月の3日間を借りて、ようやく'''白い馬'''でティル・ナ・ノグを出発した。探し回った末、オェングスはベイラの地下宮殿でブリギッドを見つけた。春分の日に二人が会うと、花が咲き、草が生え、ブリギッドのみすぼらしい服は銀のスパンコールをつけた白いローブに変わり、彼女の髪には春と夏の花が飾られた。オェングスはブリギッドと結婚し、結婚式の祝宴を開くが、ベイラはそれを妨害し、'''黒い馬'''に乗って嵐雲で二人を追い払う。やがてベイラは老いて弱くなり、若返りのために「若返りの井戸」に戻ることになるが、そこで再び眠りにつき、アンガスと花嫁は夏の王と女王になる。に乗って嵐雲で二人を追い払う。やがてベイラは老いて弱くなり、若返りのために「若返りの井戸」に戻ることになるが、そこで再び眠りにつき、アンガスと花嫁は夏の王と女王になる<ref name="Mackenzie" />。
===Scottish folklore===
In the folklore of Scotland, Angus is the fairest son of the Beira (the [[Cailleach]]), who rules over Winter. Aengus remains in [[Tír na nÓg]] all winter until he has a dream of [[Brigid]] that compels him to search the land for her. Brigid was held in captivity by the Fairy Queen who envied her beauty and forced Brigid to complete impossible chores. Angus finally leaves Tír na nÓg on his white steed by borrowing three days from August in order to search for Brigid. After searching everywhere, he eventually finds Brigid in Beira's underground palace just as Spring is beginning; when they meet on the [[imbolc|first day of spring]], flowers begin to blossom and grass grows, and Brigid's shabby clothing is transformed into white robes with silver spangles, and her hair is garlanded with spring and summer flowers. Angus marries Brigid in a wedding feast, which is disrupted by Beira, who chases them off with storm clouds on her black steed. Eventually Beira grows old and weak and has to return to the Well of Youth for rejuvenation, where she again falls asleep, and Angus and Bride become the King and Queen of summer.<ref name="Mackenzie" />
In another folktale, it is related that Beira's son Angus contradicts all of his mother's orders in an effort to become King of the Universe. Angus is "weak minded and light headed," and in punishment Beira traps her son in the rocks, where he is forced to repeat the words of others (i.e. echo).<ref name="Mackenzie2">{{cite book |last1=Mackenzie |first1=Donald Alexander |title=Wonder Tales from Scottish Myth and Legend |date=1917 |publisher=Frederick A.
