The Shadow of Calvary
Standing three feet and three inches tall, by seven feet and one inch, created this painting nearly as large as the moment it captures.  We are all well versed in the announcement of Jesus to Mary by the Angel Gabriel.  But Leonardo wanted to go deeper into the scene and actually show you, the viewer, what was happening spiritually.

Look closely into the shadow on the wall behind Mary. You see three crosses on a hill. This is the prediction of Jesus’s crucifixion at Golgotha, the hill where Jesus will give his life for the sins of the world.
