Studied again in the context of Monteverdi’s 1610 Vespers of the Blessed Virgin Mary, in research on the settings of the Magnificat. Gloria Patri, et Filio, et Spiritui Sancto, / Sicut erat in principio, et nunc, et semper, et in saecula saeculorum. Monteverdi, towards the end of his Magnificat, sets these words with that extraordinary, imitative responsory by a second tenor, as if it comes from that place halfway between earth and heaven, to the improvisatory declamation of the first. When I hear this, I recall instantly when I stood, amazed, within Basilica di San Marco in Venice. And imagine in my mind’s ear the singing and sound of this Vesper in that basilica, four hundred years ago.
