The Blessed Gabriele kneels and sees a vision of the Virgin and Child. The church, right, is San Francesco ad Alto, Ancona. The Blessed Gabriele was the Superior of this Franciscan convent, and was a member of the noble Anconese family of Ferretti. He died in 1456. His holy reputation was endorsed by the Pope in 1489. After this, the Ferretti rebuilt his tomb in San Francesco. The picture comes from this church in Ancona and was probably part of the tomb commission, hence its date.
