Lammas celebrates the Grain Harvest; the word comes from Loaf Mass and traditionally was when the first harvest came in and loaves were put on people's tables. It is celebrated on 1st August in the Northern Hemisphere, and was an important time of year for agricultural communities. It is still celebrated today with it's symbols of death and rebirth.
It's the time of the year when the power of the sun begins to fade, and darker colder days are coming. Lugh the God of Light is celebrated, and he gives his name to Lughnasadh, the Gaelic festival marking the beginning of the harvest season. The Goddess is in her aspect of Harvest Queen, Earth Mother or Grain Mother. Throughout Europe there are many customs involving cutting the grain or corn; the first and the last cutting are both significant. John Barleycorn is the living spirit of the grain and an embodiment of Lugh.
The first harvest was absolutely vital for agricultural communities, without it they would not thrive, and so a huge amount of importance was placed on it's success. Nowadays if we want a loaf of bread, we pop down to the nearest shop. However, we still rely on crops and must continue to give thanks for abundance, we must also honour the earth and it's changing seasons.
