As written before, the knowledge of all we know about the celts was discovered in only a few sources. One of these sources was the manuscripts of Julius Caesar during his conquest of Gaul. Julius Caesar had conquered Gaul but left their religion and all the customs intact. in one of his manuscripts he wrote about a god in which he named it the ‘chieftain god’ of the celts. He was not so much a warrior but more a traveler, merchant and expert craftsman. This showed the celts' appetite for discovering new places and lands. He compared the Celtic god to the Roman god Mercury. As many sources are laid down to the past, many linguists and scholars have found that this god was named Lugus. 

Sources are rare and scarce but the sources do mention a similarity in 2 other deities from other regions. Through the Irish region we can find Lugh and through the Welsh regions we can find Lleu. Both these deities bear a remarkable resemblance to Lugus. One can read upon such information in the Mabinogi. The name was supposedly meaning ‘Possessed with many talents’ or ‘Master of many crafts.’ In the Mabinogi we can read that Llue had learned many crafts. There is an episode in the tale Battle of Magh Tuireadh which mentions Lugh’s claim to be the master of all arts and crafts. 

Lugus, the Latin version or Gallo-Roman versions as mentioned, can be found in many other ways. One such way is ‘Lugdunon’ or ‘The fort of Lugus’ as linguists have translated it. Cities such as Lyon, Laon and Loudun in France, Leiden in the Netherlands and Lugo in Galicia, Spain have their names derived from Lugus. There are also several inscriptions found in Spain and also Switzerland that address Lugoves, interpreted as a Plural of Lugus. 

Not uncommon is celebrations revolving around deities. We see this happening everywhere. Lugh is no different in this. The festival of Lughnasadh which is celebrated on the first of August revolved around him. Celebrating the start of Harvest Season. During these festivities celebrations of food and games were held. Races and athletic competitions. Offering of the new first fruits as well as the sacrifice of a bull were typically held along with a ritual dance. In the more recent years these gatherings were more commonly held on top of hills and mountains but many of the same activities.
