It was the origin of the name 'Lammas' rather than the celebration itself in all it's forms.
Our ancesters took the first ripe corn, ground it into flour and baked small loaves. These were presented to the priest at the festival of the First Fruit, hence the name Loaf Mass.
My interest is the origin of words and phrases. It's this passage that gives us the expression 'and gave us this land
flowing with milk and honey'.
No doubt the celebration itself goes back further but Christianity would appear to have given us the name by which we know the festival today (I like the old word; a revel).

Lugh is, from what I've read, a sun-god in Celtic mythology, one of two gods of the harvest the other being Crom Dubh. 'Nasad' is a tribal assembly for games and like ocailleagh said, seems also to have been a festival to celebrate the beginning of harvest.
