note: See CattinS, 271-3. Cc. refers to Belcari’s Rappresentazione d’Abramo e Isacco, 1449, and alternate cc. of ‘ballo’ & ‘gli strambotti’ may be part of a single cc. indication, and may refer to one of the melodic formulas used to recite Florentine strambotti. The lines appear in the play at the moment when Isaac descends from (not ascends) the mountain (lines 393-408 in Belcari’s play).
