The reign of John the Good is remembered for the return of the bishop to the town of Milan after an exile of more than 70 years.

Actually in 569, the Lombards invaded Northern Italy and conquered its center, Milan, which was recovering from the terrible Gothic War.

John the Good was born in the diocese of Genoa in the village of Recco (although the nearby town of Camogli also claims to be his birthplace).

[3] The body of John was initially buried in the little church of Saint Michael in Domo in Milan and the first survey on his relics was made by archbishop Aribert (1018–1045).

On 24 May 1582, shortly before the demolition of the Church of St. Michael, cardinal Carlo Borromeo translated the body of John to the south transept of the cathedral of Milan, where it is still venerated.
