Rankenornament im Scheitel eines Kielbogens 

This pencil drawing by Karl Ballenberger, a prominent 19th-century artist, showcases a detailed study of a decorative element. It depicts a stylized, interwoven pattern of foliage known as "Rankenornament" positioned at the apex of a "Kielbogen," a type of pointed arch. This meticulous drawing, likely intended for architectural purposes, exemplifies the artist's keen eye for intricate details and the revival of Gothic architectural motifs during this period. The drawing, now housed in the Städel Museum, provides a valuable insight into the artistic and architectural trends of Ballenberger's time.
