The Óimelc is the feast of Brig and also a feast of prosperity in which the central offering and meal ingredient is butter and milk. Brig is the representation of the female gender as provider of milk, especially because she was the embodiment of sovereignty when Bres granted prosperity to Ireland in exchange for his life and Daghda, the owner of the Cauldron of Bounty, was his father. But Brig is also a patron of women in their functions and rights in Celtic law and society and a patron of the arts.

Several practices of the Brig’s cult survived in the feast of the saint who took her place. The Brat Bríde is a feminine practice which used to bring protection to women in child birth, to avoid sterility and to help cows with the afterbirth bringing good luck and abounded milk by putting it over their back. The Brideog procession involves the change of positions between male and female, the carrying of the doll as a symbol of Brig and fertility in to the houses, the feats of artistic presentations, the offering of butter and bread and the final meal. The craft of bindings made of rushes that were attached around the necks of the lambs to bring lucky and promote fertility. The craft of Brig’s crosses used to bless the house, the couples’ bed, seeds and fields in honor of Brig and to promote fertility.

As we have seen all these costums are related with food production, the guarantee of prosperity and fertility to the families or the society and the renovation of the position of women as part of the social structure. Being the personification of sovereignty and the land, and a goddess of poetry, healing and smith-craft Brig represents all the three functions described by Dumezil, for she is a Queen, a Druid, and an Artisan, this last function is reinforced by the milking as central product of the offerings and meal, because it is a facet of her fertility attributes that is an element of the class of production. Óimelc, being the feast of Brig, share all her sides in its meanings and practices.
