caption: The image shows a painting of a group of people on horseback in front of a city, with buildings, hills, and a sky in the background. The painting is believed to be from the 15th century, depicting the Battle of San Gimignano. The people in the painting are dressed in medieval clothing and are engaged in a fierce battle, with some of them brandishing swords and shields. The sky is a deep blue, with a few clouds scattered across it, and the buildings and hills in the distance are silhouetted against the horizon.
