Marco de' Marconi
Italian Roman Catholic religious and blessed
Feast: 24 February (not on the universal Roman calendar; kept in the Roman Martyrology or local calendars)
Who they were
Marco de' Marconi was born near Mantua in 1480 to devout parents. At sixteen, drawn to religious life, he entered the Order of the Hermits of Saint Jerome at Migliarino, near Mantua, where he lived for fifteen years hidden in prayer and mortification, dying at just thirty on 24 February 1510.
His tomb became a place of pilgrimage, and when his body was later examined it was found incorrupt; artists depicted him with a halo in Mantua, Riva del Garda, Venice, Verona, Ferrara, Rome and Naples as his veneration spread. When the convent of Migliarino was destroyed in a war between the Austrian emperor and the Duke of Mantua, his relics went with the friars, first to a new convent and church in the city and finally, after that convent was suppressed under Napoleon, to Mantua Cathedral. Pope Pius X, himself a former bishop of Mantua, confirmed his veneration in 1906.
The miracles
There was never a formal cause: he has been honoured as blessed since before the Church's formal processes began.
Why that counted as sanctity
Hermit friar of the Order of Saint Jerome near Mantua, whose body was found incorrupt after death; his veneration was confirmed by Pope Pius X in 1906.
