Little is known regarding the Hebridean sea-god Seonaidh (pronounced "shony"), who may have been a form of the sea-god known to the Irish as Lir and to the Welsh as Llyr. His name connects him with the word seonadh, signifying "augury", "sorcery", "druidism". According to Martin, the inhabitants of Lewis contributed the malt from which ale was brewed for an offering to the gods. At night a man waded into the sea up to his middle and cried out, "Seonaidh! I give thee this cup of ale, hoping that thou wilt be so good as to send us plenty of sea-ware for enriching our ground during the coming year." He then poured the ale into the sea. The people afterwards gathered in the church of St. Mulway, and stood still for a time before the altar on which a candle was burning. When a certain signal was given the candle was extinguished. The people then made merry in the fields, drinking ale.

Many of the old British and Irish deities had bird forms, and might appear as doves, swallows, swans, cranes, cormorants, scald crows, ravens, &c. The cormorant, for instance, is still in some districts called the Cailleach dubh ("the black old wife"). Some deities, like Brigit and Morrigan, had triple forms, and appeared as three old hags or as three beautiful girls, or assumed the forms of women known to those they visited. In the Cuchullin stories the Morrigan appears with a supernatural cow, the milk of which heals wounds and prolongs life. When in conflict with Cuchullin, she takes alternately the forms of an eel, a grey wolf, and a white cow with red ears. On one occasion she changes from human form to that of a dark bird. An old west of England goddess was remembered until recently in Leicestershire as "Black Annis", "Black Anny", or "Cat Anna". She frequented a cave on the Dane Hills,[182] above which grew an oak tree. In the branches of the tree she concealed herself, so that she might pounce unawares on human beings. Shepherds attributed to her the loss of lambs, and mothers their loss of children. The supernatural monster had one eye in her blue face, and talons instead of hands. Round her waist she wore a girdle of human skins.

A Scottish deity called "Yellow Muilearteach" was similarly one-eyed and blue-faced, and had tusks protruding from her mouth. An apple dangled from her waist girdle. The Indian goddess Black Kali is depicted as a ferocious being of like character, with a forehead eye, in addition to ordinary eyes, and a waist girdle of human heads. Greece had its Black Demeter with animal-head (a horse's or pig's), and snakes in her hair. She haunted a cave in Phigalia. The Egyptian goddess Hathor in her cat form (Bast) was kindly, and in her Sekhet form was a fierce slayer of mankind.[183]

Witches assume cat forms in Scottish witch lore,[184] and appear on the riggings and masts of ships doomed to destruction. There are references, too, to cat roasting, so as to compel the "Big Cat" to appear. The "Big Cat" is evidently the deity. In northern India dogs are tortured to compel the "Big Dog" (the god Indra) to send rain. "Lapus Cati" (the cat stone) is referred to in early Christian records. As a mouse was buried under an apple tree to make it fruitful, a cat was buried under a pear tree.

The Scottish "Yellow Muilearteach" revels in the slaughter of human beings, and folk poems, describing a battle waged against her, have been collected. In the end she is slain, and her consort comes from the sea to lament her death. A similar hag is remembered as the Cailleach ("the old wife"). She had a "blue-black face" and one eye "on the flat of her forehead", and she carried a magic hammer. During the period of "the little sun" (the winter season) she held sway over the world. Her blanket was washed in the whirlpool of Corryvreckan, which kept boiling vigorously for several days. Ben Nevis was her chief dwelling-place, and in a cave in that mountain she kept as a prisoner all winter a beautiful maiden who was given the task of washing a brown fleece until it became white. When wandering among the mountains or along the sea-shore she is followed, like Artemis, by herds of deer, goats, swine, &c. The venomous black boar is in some of the stories under her special protection. Apparently this animal was her symbol as it was that of the Baltic amber traders. The hero who hunts and slays the boar is himself killed by it, as was the Syrian god Adonis by the boar form of Ares (Mars). In Gaul the boar-god Moccus was identified by the Romans with Mars.

In Gaelic stories the hero who hunts and slays the boar is remembered as Diarmid, the eponymous ancestor of the Campbell clan. Apparently the goddess was the ugly hag to whom he once gave shelter. She transformed herself into a beautiful maiden who touched his forehead and left on it a "love spot".[185]

When she vanished he followed her to the "Land-Under-Waves". There he finds her as a beautiful girl who is suffering from a wasting disease. To cure her he goes on a long journey to obtain a draught of water from a healing well. This water he carries in the "Cup of Healing".
