Prophet mit Buch auf Wolken schwebend 

This pen-and-ink drawing by the Italian Baroque artist Luca Giordano depicts a prophet seated on clouds holding a book. The figure is depicted in a dynamic pose with an outstretched arm and an expressive face, characteristic of Giordano's style. The detailed depiction of the figure and the flowing drapery create a sense of movement and energy, showcasing Giordano's mastery of draftsmanship. This drawing is a study for a larger composition, likely an altarpiece or a fresco, and highlights the artist's preparatory process.
