On Maundy Thursday, the consecration of the Holy Oils and other ceremonies overshadow almost entirely the commemoration of the important event which took place on that day—the institution of the Holy Eucharist. It was this fact which suggested the introduction of a festival specially intended to commemorate that event, as is expressly stated in the papal constitution _Transiturus_. The introduction of this feast dates from a comparatively late time, and its adoption is limited to the West, although the Uniat Greeks have also partially accepted it. The earliest trace of a special reference to the Holy Sacrament of the altar in the public worship of the Church is probably the appearance of the name _Natalis Calicis_, in the Calendar of Polemius Silvius, on the 24th March. In order to understand this entry, it must be remembered that anciently the 25th March was often regarded as the day on which Christ died (_vide ante_, p. 57). Divine Providence made use of a humble nun to further the introduction of this festival. Juliana,[273] born at Retinne, near Liège, in 1193, was received as an orphan into the cloister, and became a nun of the order of St Augustine. She was appointed prioress of the lazar-house of _Mons Cornelii_ (Mont-Cornillon), near Liège, where she passed the greater part of her life. When this institution received another prior who fell out with the authorities of Liège over some matters of administration, Juliana was obliged to leave the lazar-house in 1240. She took up her abode in Liège, with a kindred spirit, the recluse Eve. She returned to Mont-Cornillon after three years, but when fresh disagreements broke out again, on the death of Bishop Robert († 1246), she was compelled to leave Liège altogether. She found a refuge with the Cistercian nuns at Salsinnes in the diocese of Namur. But this convent was destroyed in the wars which then disturbed the country, and Juliana was once more destitute. She ended her life on the 5th April 1258, as a recluse at Fosses, where she had found a refuge, and was buried in the monastery of Villiers, in the diocese of Namur.
