Midnight
It was naturally supposed that Lorenzo and his Attendants were conducted thither by the same design . The Duke of Medina being recognised , the People drew back , and made way for his party to advance . Lorenzo placed himself opposite to the great Gate , through which the Pilgrims were to pass . Convinced that the Prioress could not escape him , He waited patiently for her appearance , which She was expected to make exactly at Midnight . The Nuns were employed in religious duties established in honour of St. Clare , and to which no Prophane was ever admitted . The Chapel windows were illuminated . As they stood on the outside , the Auditors heard the full swell of the organ , accompanied by a chorus of female voices , rise upon the stillness of the night .
