Lúnasa

The beginning of August marks the old Irish Gaelic festival day of Lúnasa, halfway between summer solstice & autumn equinox, marking the beginning of harvest time and the turn from summer to winter. (In Irish, the word for August is Lúnasa.) It is a time to honor the sun, for Lúnasa (or Lughnasadh) is named for Lugh, the old Irish god of the Sun. It's a time to gather the first harvests, to light a bonfire in thanks for your blessings, bake a pie with freshly gathered blueberries, for matchmaking and hand-fasting, for pilgrimages to holy wells and sacred trees. Here Lúnasa arrived on a cool front, one I was aching for, a blessed foreshadowing of Autumn and all her finery. Happy Harvest to come.
