I was looking to edit another motet by the Baroque Florentine Francesco Feroci, and opened his O magum mysterium, to discover that the piece is a flagrant ripoff of Victoria's great setting! The triple-time section in the Alleluia is missing, but the rest is there. There are one or two details that I'd rewrite before using, but overall, it's a successful transcription. And if you'd like to do Victoria but only have TTB or SSA, this is for you
