O how delightful, * o Lord, is thy Spirit, Who, that Thou may show Thy sweetness unto Thy children, having granted them most sweet bread from heaven, fillest the hungry with good things, and sendest away empty the scornful rich. (The Magnificat antiphon for First Vespers of Corpus Christi.)
Aña O quam suávis est, * Dómine, spíritus tuus, qui, ut dulcédinem tuam in filios demonstráres, pane suavíssimo de caelo prǽstito, esurientes reples bonis, fastidiósos dívites dimittens inánes.
A very nice polyphonic setting by the Spanish composer Alonso Lobo (1555-1617), a contemporary of Victoria, who held him in the highest regard.
Another by William Byrd (1540 ca. - 1623)
A particularly fine recording of the Gregorian melody of the hymn Pange, lingua, gloriosi Corporis mysterium, which is sung at both Vespers.
And finally, an absolutely splendid version by Victoria himself, alternating a different Gregorian melody with polyphony.
