O gloriosa domina excelsa super sidera qui te creavit provide lactas sacrato ubere | Quod Eva tristis abstulit tu reddis almo germine intrent ut astra flebiles sternis benigna semitam | Tu regis alti janua et porta lucis fulgida vitam datam per virginem gentes redemptae plaudite | Patri sit paraclito tuoque nato gloria qui veste te mirabili circumdederunt gratiae
