Ad Mortem Festināmus is a monodic song (fol. 26v) from the Llibre Vermell de Montserrat, one of the oldest extant medieval manuscripts containing music. Its lyrics talk about the inevitability of death and the need to stop sinning. It has been recorded by a variety of artists, including the electronic neo-medieval act Qntal, that gave new music to the lyrics and made it a club hit in 1992.The manuscript was prepared in approximately 1399. It originally contained 172 double pages, of which 32 have been lost. 6 folios contain music. The title "The Red Book of Montserrat" describes the red binding in which the collection was placed in the 19th century. No composer is identified for any of the songs it contains. The monastery holds the shrine of the Virgin of Montserrat, which was a major site of pilgrimage during the time it was compiled.
Scribere proposui de contemptu mundano ut degentes seculi non mulcentur in vano iam est hora surgere a sompno mortis pravo a sompno mortis pravo Vita brevis breviter in brevi finietur mors venit velociter quae neminem veretur omnia mors perimit et nulli miseretur et nulli miseretur. Ad mortem festinamus peccare desistamus peccare desistamus. Ni conversus fueris et sicut puer factus et vitam mutaveris in meliores actus intrare non poteris regnum Dei beatus regnum Dei beatus. Tuba cum sonuerit dies erit extrema et iudex advenerit vocabit sempiterna electos in patria prescitos ad inferna prescitos ad inferna. Ad mortem festinamus peccare desistamus peccare desistamus.
