SIBYL . English, Frank Kidson (Musical Times, Feb. 1, 1911, p. 94) notes that Edward Jones's "Sibyl", published 1784 and again in 1794, is an appropriation of a lesson in Scottish publisher Robert Bremner's Harpsichord and Spinnet Miscelany entitled "Cibel." Kidson points out that a 'Cibel' is an obsolete dance measure, and takes Jones to task for changing the spelling and meaning of the name ("without a word of comment at his appropriation"), adding a "mystic flavour which the mere name of a dance measure would not give."
