In Jena ist es Brauch, dass frischgebackene Doktor*innen einen Kranz über das Schwert vom Hanfried (Statue von Johann Friedrich I. von Sachsen, dem Begründer der Universität) auf dem Marktplatz werfen.(Das Foto zeigt einen Kranz, der in die Höhe geworfen wird und sein Ziel hoffentlich nicht verfehlt.
