Who they were

Abbo was born near Orléans about 945 and became a monk of the Benedictine monastery of Fleury-sur-Loire, notable for both learning and holiness. He studied philosophy, mathematics and astronomy, and early in life was called to England to direct the school of the new monastery of Ramsey.

Elected abbot of Fleury after a contested election settled in his favour by Gerbert, the future Pope Sylvester II, he became one of the great lights of the Church in the stormy times of Hugh Capet and the Ottos, trusted by Pope Gregory V. He died at Fleury on 13 November 1004.

The miracles

There was never a formal cause: he has been honoured as a saint since before the Church's formal processes began.

Why that counted as sanctity

A monk of learning and holiness who served the Church in a turbulent age.
