About the name
Lugh is the Irish god of every skill at once — the Samildánach, master of all arts, who talks his way into Tara by being the only one present who can do everything. Lughnasadh, the harvest festival he founded for his foster-mother, still names the month of August in Irish.
The meaning is genuinely unsettled. The old reading was Indo-European *leuk-, light, which suited a figure long treated as a sun god; the reading philologists now prefer is *leug-, oath or binding. Both are defensible and this page will not pretend otherwise.
