Joshua is at the forefront of the left group, he charges the king of the Amalekites

A group of medieval knights in chainmail and nasal helmets clash on horseback in a stylized Romanesque composition. Joshua, identified by an inscription, leads the charge from the left while casualties and a downed horse lie in the foreground. The scene is rendered with the characteristic flat perspective and vibrant color blocks typical of high medieval manuscript illumination.

The Hortus Deliciarum was a seminal medieval encyclopedia that synthesized biblical history with the liberal arts, representing an early attempt at a unified system of knowledge. It illustrates the medieval pedagogical tradition that sought to map the history of salvation through visual narrative, preceding the more specialized esoteric and philosophical systems of the Renaissance.
