According to O’Neill, who fails to reveal his source [which, considering the context and details, is most probably Flood's »Story...«], "the Cuisleannach or pipes were among the favorite musical instruments at the great triennial "Feis" at Tar, which continued from pre-Christian days to the year 560 AD, when the glories of "Tara’s Hill" came to an end"; NB¹: Oddly, in his »History of Irish Music« (Dublin, 1905) Flood defines the identical term as a "player on the bag-pipes" (➺ homonym).
