What story did Jan van Eyck tell through art?

Jan van Eyck is known as an innovator of veristic realism, not only for his meticulous portraiture but also for his stunning panoramic landscapes that appear to recede far into the distance. Predating the naturalistic landscapes of Leonardo da Vinci by over 50 years, paintings such as Saint Francis of Assisi Receiving the Stigmata demonstrate the Eyckian use of atmospheric perspective, and anticipate the later genre of the Baroque Dutch landscape tradition. Jan van Eyck positioned this scene in the rocky mountains of the legend, yet also included a miniature bustling Netherlandish city in the distance using his microscopic painting technique, a common trait of early Netherlandish book illumination and religious paintings. The style of the city's rendering lends credence to the theory of the artist's early career as a miniaturist, as the anonymous "Hand G" of the Turin-Milan hours.
