Saint John the Baptist from Griffoni Altarpiece Francesco del Cossa (1436-1478)

The picture has something of this: saint, god, holy, spirituality, sacred, church, ancient, people, gold, Renaissance, religious belief, religious, sculpture, worship, statue, woman.
Perhaps it’s a painting of a man wearing a red dress and holding a staff in his right hand and a banner in his left hand, with a city in the background.
