Vitaliano di Osimo
Feast: 16 July (not on the universal Roman calendar; kept in the Roman Martyrology or local calendars)
Who they were
Vitaliano was bishop of Osimo in the 8th century; his existence is firmly documented by a contemporary funerary inscription kept in the crypt of the city's cathedral. He took part in the Roman council of 743, which confirms his historical standing and recognition in Rome. Tradition credits him with rebuilding the cathedral dedicated to Saint Leopard, the city's first bishop, where he was later buried.
Nothing else is known of his life. His veneration is attested from at least the early 17th century, and in 1755 the town council of Osimo officially listed him among the city's patron saints; there was never a formal act of canonisation, since his veneration was confirmed by ancient, uninterrupted custom under the rules that predate the centralised causes of canonisation. Some scholars once tried to identify him with the 7th-century Saint Vitalian of Capua, who shares the same 16 July feast, but modern scholarship rejects this: the Osimo inscription confirms a distinct 8th-century bishop.
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
8th-century bishop of Osimo, confirmed by a contemporary funerary inscription; venerated as patron of the city by ancient, uninterrupted custom (formally listed among Osimo's patrons in 1755).
