Jesus on the Cross, by Fra Angelico
This is St. Francis receiving
the stigmata from an angel.
In the later Middle Ages in Europe, very holy Christian people sometimes got these marks on their own hands and feet. People thought this was a sign that God really loved them a lot, and that they were especially holy people. Many people who had these marks became saints after they died.
One famous example of a man who people said had gotten stigmata from God was Francis of Assisi.
Learn by doing: go look at medieval paintings online or in a museum. Are there any stigmata?
