I got a chance to study in Florence and during that time I visited the Convent of San Marco where Fra Angelico had painted frescos.

Those frescos were painted in the monastic cells on the second floor of the dormitory. On either side of the hallway, large bright windows cast almost blinding light through the floor.
When you entered a monk's cell, your eyes had to adjust for there was only a small window against the far wall. Next to that window, you could barely make out an image.

A crown of thorns, a man spitting, a stick, a couple of hands waving. As your eyes adjusted you realized...

There was no body to the face spitting, in fact no bodies at all, none holding the stick or supporting the hands. The only body Fra Angelico needed was that of Christ.

I didn't need those bodies to project my vision of the story. Fra Angelico deliberately left out those details because they were not important to the story - a story that focuses on Christ's torment. Fra Angelico had opened the space for the monks to imagine the torture, the scene.

A work of art does not need to include everything. The artist needs to trust their viewers. Provide the space for interpretation.
