While the scaffold was being arranged for Beatrice, and whilst the Brotherhood returned to the chapel for her, the balcony of a shop filled with spectators fell, and five of those underneath were wounded, so that two died a few days after.  Beatrice, hearing the noise, asked the executioner if her mother had died well, and, being replied that she had, she knelt before the crucifix, and spoke thus:  “Be thou everlastingly thanked, O my most gracious Saviour, since, by the good death of my mother, thou hast given me assurance of thy mercy towards me.”  Then, rising, she courageously and devoutly walked towards the scaffold, repeating by the way several prayers with so much fervour of spirit that all who heard her shed tears of compassion.  Ascending the scaffold, while she arranged herself, she also turned her eyes to Heaven, and thus prayed:  “Most beloved Jesus, who, relinquishing thy divinity, becamest a man, and didst through love purge my sinful soul also of its original sin with thy precious blood; deign, I beseech thee, to accept that which I am about to shed, at thy most merciful tribunal, as a penalty which may cancel my many crimes, and spare me a part of that punishment justly due to me.”  Then she placed her head under the axe, which, at one blow, was divided from her body as she was repeating the second verse of the psalm De profundis, at the words fiant aures tuae.  The blow gave a violent motion to her body, and discomposed her dress.  The executioner raised the head to the view of the people; and in placing it in the coffin placed underneath, the cord by which it was suspended slipped from its hold, and the head fell to the ground, shedding a great deal of blood, which was wiped up with water and sponges....  The bodies of Lucretia and Beatrice were left at the end of the bridge until the evening, illuminated by two torches, and surrounded by so great a concourse of people that it was impossible to cross the bridge.  An hour after dark, the body of Beatrice was placed in a coffin, covered by a black velvet pall richly adorned with gold:  garlands of flowers were placed, one at her head, and another at her feet; and the body was strewed with flowers.  It was accompanied to the church of S. Peter in Montorio by the Brotherhood of the Order of Mercy, and followed by many Franciscan monks, with great pomp and innumerable torches.  She was there buried before the high altar, after the customary ceremony had been performed.  By reason of the distance of the church from the bridge, it was four hours after dark before the ceremony was finished.  Afterwards, the body of Lucretia, accompanied in the same manner, was carried to the church of S. Gregorio upon the Celian hill; where, after the ceremony, it was honourably buried.

Beatrice was rather tall, of a fair complexion, and she had a dimple on each cheek, which, especially when she smiled, added a grace to her lovely countenance that transported every one who beheld her.  Her hair appeared like threads of gold; and, because they were extremely long, she used to tie it up, and when afterwards she loosened it, the splendid ringlets dazzled the eyes of the spectator.  Her eyes were of a deep blue, pleasing, and full of fire.  To all these beauties she added, both in words and action, a spirit and a majestic vivacity that captivated every one.  She was twenty years of age when she died.
