Note 49 — THE BOOK OF THE DEAN OF LISMORE.
Thomas Maclauchlan translation
Bran was the famous hound of Finn. The word means “a raven,” but used as an adjective it signifies “black,” which is apparently the origin of the name. Another of his dogs was called “Luath,” or “Swift,” also an adjective. These are common names for staghounds in the Highlands at this day. Reference is made a few lines before this to a white dog, “achoin ghil,” translated “snow-white,” “geal,” implying the most intense whiteness.
