Final answer:
Yes, tradition holds that King David wrote most of the Psalms, as reflected in historical art such as the Paris Psalter, which features him as a musician and composer.
Step-by-step explanation:
According to tradition, King David is considered to have written most of the Psalms. This connection to David is emphasized in historical art and traditions, such as in the Paris Psalter, a remarkable illuminated manuscript which contains 14 full-page illustrations in its 449 folios. In eight of these images, David is depicted as a musician and composer, highlighting his traditional association with the Psalms. These illustrations are not just works of art but also served as political propaganda, depicting King David as an exemplary ruler, which resonated with the medieval ideals of kingship. Therefore, the tradition states that David was a psalmist, and this is often reflected in historical and artistic depictions of him.
