Summary: The early Latin Easter office hymn Aurora Lucis Rutilat ("Heaven with rosy morn is glowing"), traditionally ascribed to Ambrose, sings the harrowing of hell: the risen Christ despoils the realm of the dead — "Hell is writhing in despair" — and "leads his saints to life and light," putting the descent-and-liberation into the Church's worship. (The ascription to Ambrose himself is traditional, not certain — see Notes.)
Heaven with rosy morn is glowing,
Songs of triumph fill the air,
Strains of praise from earth are flowing,
Hell is writhing in despair.Earth's great king, in glory springing,
From the deep sepulchral night,
While loud anthems round are ringing,
Leads His saints to life and light.
— Aurora Lucis Rutilat ("Heaven with rosy morn is glowing"), tr. John Williams, hymnary.org. The hymn frames Easter as a contest of realms: as heaven and earth break into triumph, the underworld below recoils — "Hell is writhing in despair." The risen "Earth's great king" rises "from the deep sepulchral night" not alone but as a deliverer, leading "His saints" — the righteous dead who waited below — out "to life and light." This is the descent-and-liberation (the harrowing of hell) cast as liturgy: the soul's interim sojourn among the dead, and Christ's breaking of that captivity, sung in the Church's Easter worship.
