Milanese Chronicles from the 16th century report a short stay of the Shroud in Milan: it was taken there by the Dukes of Savoy, who fled Turin after the invasion by French forces. The ostension of the Shroud took place outside the Sforza Castle, on the barbican facing the town, in front of a multitude of people. Sources do not state who actually planned the ostension (probably Beatrice of Savoy). According to some historians, the initiative was promoted by a hermit close to St. Antonio Maria Zaccaria, but the assumption appears to be a misintepretation of a single source, suggested by the strong symbolic bond between the Shroud
and the so-called Eucharistic Quarantore (Forty Hours’ Adoration), a devotion originated in Milan in the same period.
