Patron of the Arts:

Similar to the Roman god Mercury, Lugh was known as a god of both skill and the distribution of talent. There are countless inscriptions and statues dedicated to Lugh, and Julius Caesar himself commented on this god's importance to the Celtic people. Although he was not a war god in the same sense as the Roman Mars, Lugh was considered a warrior because to the Celts, skill on the battlefield was a highly valued ability. In Ireland, which was never invaded by Roman troops, Lugh is called sam ildanach, meaning he was skilled in many arts simultaneously.

Lugh Enters the Hall of Tara:

In one famous legend, Lugh arrives at Tara, the hall of the high kings of Ireland. The guard at the door tells him that only one person will be admitted with a particular skill -- one blacksmith, one wheelwright, one bard, etc. Lugh enumerates all the great things he can do, and each time the guard says, "Sorry, we've already got someone here who can do that." Finally Lugh asks, "Ah, but do you have anyone here who can do them ALL?" At last, Lugh was allowed entrance to Tara.
