Happy Lughnasadh! As I suspect just about everyone reading this knows, today is the usual day for observing the feast day of Lugh, the Irish god of many skills, as well as a celebration of the first phase of the harvest and the start of autumn. Lugh is described as one of the pan-Celtic gods based on common names and overlapping functions within the set of pre-Christian European tribes commonly called Celts these days. It was originally a two-week festival, but it's rare to find any pagan individual or group nowadays with that kind of time who'd have the money to throw that sort of party.
For an excellent essay on Lugh/Lugus, I recommend Alexei Kondratiev's writeup on the subject.
Brian Walsh has set up an online shrine to the Many-Gifted Lord. If you don't have time to do a full ritual, a visit there wouldn't hurt.
Lugh is one of my patrons, though only since last year after Lughnasadh had already passed. I am grateful to Him for His encouragement, advice, and butt-kicking this year. Hail Lugh!
