John Cantius - Biography

Biography

He was born in Kęty, a small town near Oświęcim, in the diocese of Kraków, Poland, to Stanisław and Anna Kanty. He attended the Kraków Academy at which he attained bachelor, licentiate, and doctor. Upon graduation he spent the next three years preparing for the priesthood, at the end of which he was ordained.

Upon his ordination, he was offered a professorship at another university, which he accepted. While there, he was offered a professorship of Sacrae Scripturae (Sacred Scripture) back at the Jagellonian. He accepted, and held the professorship until his death in 1473. In physics, he helped develop Jean Buridan's theory of "impetus," which anticipated the work of Galileo and Newton.

John Cantius was noted throughout his life for his good humor and humility. He subsisted only on what was strictly necessary to sustain his life, giving alms regularly to the poor. He made one pilgrimage to Jerusalem with the desire of becoming a martyr among the Turks, and four pilgrimages to Rome, all on foot.

Michael Miechowita, the medieval Polish historian and the saint's first biographer, described the saint's extreme humility and charity; he took as his motto:

Conturbare cave: non est placare suave,

Infamare cave; nam revocare grave.

(Beware disturbing: it's not sweetly pleasing,

Beware speaking ill: for taking back words is burdensome.)

He died while living in retirement at his alma mater on 24 December 1473, aged 83. His remains were interred in the Church of St. Anne, Kraków, where his tomb became and remains a popular pilgrimage site.
