"Do Do nyztyngale syng wel miry
Shal y nevre for zyn love lengre kary."
"Hew alas p amor
Oy moy myst en tant dolour."
"Hey how ze chevaldoures woke al nyght."
It is quite evident that these lines were thus prefixed (as is still the custom), to indicate the air to which the Latin hymns were to be sung. This is also set forth in a memorandum at the commencement, which states that these songs, Cantilene, were composed by the Bishop of Ossory for the vicars of his cathedral church, and for his priests and clerks,
"ne guttura eorum et ora deo sanctificata polluantur cantilenis teatralibus turpibus et secularibus: et cum sint cantatores, provideant sibi notis convenientibus, secundum quod dictamina requirunt."—Lib. Rub. Ossor. fol. 70.
