Explanation:

Drusus led the army via Rödgen through the territories of the Marsi and Cherusci until he even crossed the river Elbe.[51] Here he is said to have seen an apparition of a Germanic woman who warned him against proceeding farther and that his death was near. Drusus turned back,[52] erecting a trophy to commemorate his reaching the Elbe, perhaps on the site of Dresden or Magdeburg.[53]
