Crop circle 2003 Hackpen Hill, England

Lughnasadh is the first of three Pagan harvest festivals—Mabon and Samhain being the others. It is a celebration of the ripening of grain, a time for reaping that which has been sown and for honouring the bounty of nature.

Lughnasadh means ‘Lugh’s assembly’, referring to Lugh, the sun god of Celtic mythology; the name Lammas (from Old English hlaf maesse, ‘loaf mass’) is also used for this festival, taken from a medieval Christian observance occurring at around the same time.
