note: CattinNF, 200; Diederichs, 246-51. Music ed. CattinG, no.19 (Grey), w/notes on xxii; CattinCon, 68-9 (Pav361); Diederichs, 430-2 (Pav361 & Grey), and LuisiLG, ii, 12-14 (Grey,Pav361 & PetL/i versions, which are unrelated). B207 version, also unrelated to the others, ed. in EynardLP, 84-5. Text ed. LuisiLG, i, 287-8, and found in Gall3 without cc. Text entered in R2929, which was copied by 1448, so it is likely to have been known in Florence with a modo proprio setting (implied by its entry in Gall3 without a cc. title), possibly one of those transmitted in the above non-Florentine sources.
