Composed by Allegri in 1638 especially for the Vatican, where he was a singer in the Sistene Chapel. It was only sung during Passiontide and the music scores were carefully locked away so no-one else could use it. It was regarded as so special that the Pope ordered that only 3 copies ever left the Vatican: one for the Padre Martini, one for the King of Portugal and one for Holy Roman Emperor.
