Final answer:
The Bible celebrates David as a hero and a poet who composes psalms. He is depicted in medieval art, typically playing his harp, and is a central figure in various narratives involving military conquests and royal disputes.
Step-by-step explanation:
The Bible celebrates David as a hero who vanquishes the giant Goliath and as a poet who composes psalms still recited today. In medieval art, he is often depicted as a model of just rule for kings and traditionally considered the author of the Psalms. In the Paris Psalter, an illuminated manuscript from around 900 CE, King David is shown as a musician and composer, playing his harp amidst classical personifications, such as Melody. This imagery connects to the classical tragic figure of Orpheus and represents a blend of Christian and pagan classical traditions. Moreover, the Bible describes the various military conquests and acts under David's rule as well as his role in the narratives of Saul, Samuel, and his family's dynamics.
