Christian liturgical traditions and evening prayers

The 'Te lucis ante terminum' is an ancient Christian hymn used during Compline, the final prayer of the Liturgy of the Hours. Its origins trace back to early Western monasticism and were formally codified in the Rule of Saint Benedict during the 6th century. The hymn serves as a spiritual request for divine protection during the night, asking for the removal of 'night phantasms' and spiritual temptations.

Beyond its historical roots, the hymn is noted for its theological reflection on human fragility and its musical structure, which follows the Ambrosian hymn scheme of iambic dimeter quatrains. This structure was designed to facilitate choral singing and memorization. Throughout history, the hymn has been set to music by various sacred music composers, ranging from Palestrina to Victoria.

Complementary evening practices include various prayers to the Holy Trinity and invocations such as those by Saint Augustine, intended to facilitate spiritual conversion and peaceful rest through faith, hope, and charity.
