Lughnasadh
Lughnasadh is a traditional mid-summer harvest festival, The name Lughnasadh itself, which means 'corn king' is of Southern Irish origin, and relates to the harvest of early wheat in these areas. Lughnasadh was a time for feasting and games, much like the modern Olympic Games, and took place around the time of the first harvest. Games of this form can be seen in the traditional Scottish Highland Games which take place during the summer months.
In Irish mythology, Lugh, who symbolises the harvest, is brought to find a wife. However, none can be found and one is fashioned for him out of flowers. However, his flower bride is lured away by another and Lugh is killed in the ensuing battle. The killing of Lugh symbolises both the harvest, and the end of summer, which is seen at Samhuinn.
It is a common tradition at Lughnasadh for hand-fastings to take place. These are a form of marriage, where each party agrees to remain together for a year and a day - if after this time they are still together they would be considered man and wife, but if they wished to part they could do so after this time.
