A penitent of the Third Order of St. Francis, born at Laviano in Tuscany in 1247; died at Cortona, 22 February, 1297. At the age of seven years Margaret lost her mother and two years later her father married a second time. Between the daughter and her step-mother there seems to have been but little sympathy or affection, and Margaret was one of those natures who crave affection. When about seventeen years of age she made the acquaintance of a young cavalier, who, some say, was a son of Gugliemo di Pecora, lord of Valiano, whith whom she one night fled from her father’s house. For nine years she lived with him in his castle near Montepulciano, and a son was born to them. Frequently she besought her lover to marry her; he as often promised to do so, but never did. Even during this period Margaret was very compassionate towards the poor and relieved their wants; she was also accustomed to seek out quiet places where she would dream of a life given to virtue and the love of God.
She was at last set free from her life of sin by the tragic death of her lover, who was murdered whilst on a journey. It was characteristic of her generosity that she blamed herself for his irregular life, and began to loathe her beauty which had fascinated him. She returned to his relatives all the jewels and property he had given her and left his home; and with her little son set out for her father’s house. For a moment she felt tempted to trade upon her beauty; but she prayed earnestly and in her soul she seemed to hear a voice bidding her go to the Franciscan Friars at Cortona and put herself under their spiritual direction. On her arrival at Cortona, two ladies, noticing her loneliness, offered her assistance and took her home with them. They afterwards introduced her to the Franciscan Friars at the church of San Francesco in the city.
For three years Margaret had to struggle hard with temptations. Naturally of a gay spirit, she felt much drawn to the world. But temptation only convinced her the more of the necessity of self-discipline and an entire consecration of herself to religion. At times remorse for the past would have led her into intemperate self-mortifications, but for the wise advice of her confessors. As it was, she fasted rigorously, abstaining altogether from flesh-meat, and generally subsisting upon bread and herbs. Her great physical vitality made such penance a necessity to her.
After three years of probation Margaret was admitted to the Third Order of St. Francis, and from this time she lived in strict poverty. Following the example of St. Francis, she went and begged her bread. But whilst thus living on alms, she gave her services freely to others; especially to the sick-poor whom she nursed. It was about the time that she became a Franciscan tertiary that the revelations began which form the chief feature in her story. But Margaret, though coming to lead more and more the life of a recluse, was yet active in the service of others. She prevailed upon the city of Cortona to found a hospital for the sick-poor, and to supply nurses for the hospital, she instituted a congregation of Tertiary Sisters, known as le poverelle. She also established a confraternity of Our Lady of Mercy; the members of which bound themselves to support the hospital, and to help the needy wherever found, and particularly the respectable poor. Moreover on several occasions Margaret intervened in public affairs for the seek of putting an end to civic feuds. Twice in obedience to a Divine command, she upbraided Guglielmo Ubertini Pazzi, Bishop of Arezzo, in which diocese Cortona was situated, because he lived more like a secular prince and soldier, than like a pastor of souls. This prelate was killed in battle at Bibbiena in 1289.
The year previous to this, Margaret for the sake of greater quiet had removed her lodging from the hospital she had founded to near the ruined church of St. Basil above the city. This church she now caused to be repaired. It was here that she spent her last years, and in this church she was buried. But after her death it was rebuilt in more magnificent style and dedicated in her own name. There her body remains enshrined to this day, incorrupt, in a silver shrine over the high-altar. Although honored as a beata from the time of her death, Margaret was not canonized until 16 May, 1728.
