The present plaques are after fresco fragments by Melozzo da Forlì, now in the Pinacoteca Vaticana.  The original fresco was in the vault of the church of Santi Apostoli in Rome, painted crica 1479-89 for Cardinal Giuliano della Rovere, later Julius II. Melozzo da Forlì (c. 1438 - 1494), was an Italian Renaissance painter near the Umbrian school, the first who successfully practiced the foreshortening technique so well rendered in the present lot.
