Lammas Day, celebrated on August 1, has many names, but the most common among them is Lughnasadh, which translates as "Lug's gathering" or "Lug's wedding." Lug is one of the gods of the Celtic pantheon, the patron of agriculture and many crafts. The Celts called him "long-armed" and "many skillful."
An ancient legend about the origin of this holiday has been preserved: Lug allegedly established it in honor of his adoptive mother, the goddess Tailtine, after her death. The image of this goddess is associated with the earth, fertility, because her name "Tailtin" comes from the word "talam" - earth.
The holiday Lughnasad was not only cattle-breeding, but also agricultural: it marked the transition of one season to another. In ancient Celtic sources, when listing all the holidays, the day of Lughnasad was interpreted as "the time of the beginning of the harvest", the period when "the earth suffers under the weight of its fruits."
