During the 1930s, she published folk stories in various magazines, and after the Second World War she began to write books for teenage readers, concentrating predominantly on retelling classical and medieval legends and myths.
Her extremely wide range of adaptations drew from Ancient Greek and Roman myths (Hercules, the Iliad, the Odyssey, the Golden Fleece and the Aeneid) as well as (King Arthur, The Song of the Nibelungs, Roland and Parzival).
Among the well-known artists who provided illustrations for her works were Hans Vonmetz, Maria Rehm, Josef Widmoser and Alfred Kunzenmann.
