Saint Daig (d. 588?) was an Irish Christian bishop and confessor of Inis-Caoin-Deagha (now Inniskeen, County Monaghan), who lived towards the end of the 6th century. His name in Gaelic means "A great flame" and he was probably named after his mother Deighe.
"Daig" is an expression common in Basel and the Deutschschweiz and refers to a milieu consisting of wealthy families from the swiss city of Basel. These families had full civic rights in the then city-state since the High Middle Ages and are known for their particular idiosyncratic habits and a dialect distinct from that of the rest of the population. For centuries the Daig was the social, political and economic elite of Basel and it still is today, if less exclusively.
