Broederlam, Melchoir (Flemish, active 1381-1409) Flemish painters

The picture has something of this: people, saint, god, sculpture, blood, symbol, decoration, religious belief, holy, temple, lion, man, veil, spirituality, church.
Perhaps it’s a close up of a painting of a man with long hair and a beard wearing a red robe and holding a cross with red feathers around his neck.
