Spain was a latecomer to the cyclic Mass, which began to develop there in the 1490s or late 1480s. A number of different strands in this process – free single movements, mix-and-match Masses, ferial Masses, imports, three-voice Masses, Missae sine nomine and the six cycles of Francisco de Peñalosa – can usefully be separated and laid at least tentatively onto a chronological framework on the basis of manuscript date and composer biography. The surviving evidence seems to show a tradition that arose with particular energy in the decade or so after 1500 and reached maturity within a single generation.
