‘Although finn strictly means a colour, it is used to designate water that is clear or transparent. In this way is formed the name Finglas from glais, a little stream: Finn-glais (so written in many old authorities), Crystal Rivulet.’

– Joyce, P. W. (The Origin and History of
Irish Place Names, Vol. II, 1883)

‘But you’ll have to ask that same four that named them is always snugging in your barsalooner, saying they’re the best relicts of Conal O’Daniel and writing Finglas Since the Flood. That’ll be some kingly work in progress.’

– Joyce, James (Finnegans Wake)
