Life
He entered the Society of Jesus at Avignon, in 1626. For eight years he taught philosophy and for six years mathematics at the Jesuit college at Lyons, attracting many pupils. Called to Rome, he became the theologian of the court of the papal penitentiary in the Vatican basilica, a position he held for thirty years.
Fabri was a highly respected scientist among his contemporaries. He was elected to the Accademia del Cimento in 1657, the year the Academy was founded.Leibniz placed him with Galileo, Torricelli, Steno and Borelli for his work on elasticity and the theory of vibrations, and alone with Galileo for his efforts to 'rationalise experimental kinematics'. Mersenne rated him 'a veritable giant in science'
Works
Sommervogel mentions thirty-one titles of published works in connection with Fabri's name, besides fourteen of his productions in manuscript, in the Library of Lyons.
The following are the more important of his publications:
This work was attacked by Stephanus Gradius, Prefect of the Vatican Library, in his Disputatio de opinione probabili (Rome, 1678; Mechlin, 1679).
This treats, in eleven dialogues, of probabilism, explaining its true nature, and refuting the charges of its opponents. The Cologne edition was considerably enlarged but did not meet with ecclesiastical approbation; it was placed on the Index of forbidden books soon after its appearance.
The principles on which this work constructs its theological conclusions are far different from those of Aristotle.
Most of Fabri's other works deal with philosophy, mathematics, physics, astronomy, and even zoology. In his treatise on man he claims to have discovered the circulation of the blood, prior to William Harvey, but after having investigated this question, Father Auguste Bellynck arrives at the conclusion that, at best, Father Fabri may have made the discovery independently of Harvey.
