Happy Easter to You and Yours from Semiduplex.

Victimæ paschali laudes
immolent Christiani.

Agnus redemit oves.
Christus innocens Patri
reconciliavit
peccatores.

Mors et vita duello
conflixere mirando.
dux vitæ mortuus
regnat vivus.

“Dic nobis, Maria,
quid vidisti in via?”
“Sepulchrum Christi viventis,
et gloriam vidi resurgentis,

“Angelicos testes,
sudarium et vestes.
Surrexit Christus spes mea;
praecedet suos in Galilaea.”

[…]

Scimus Christum surrexisse
a mortuis vere;
tu nobis, victor rex, miserere!

(Wipo of Burgundy’s Easter sequence “Victimæ paschali laudes,” 11th c., has survived nine hundred years of liturgical reforms, beginning with Pius V’s Tridentine reforms and concluding most recently with the retranslation of the Roman Missal under Benedict XVI.)
