Schiller's participation in the student play 'Der Preis der Tugend, in laendlichen Unterredungen und allegorischen Bildern von Goettern und Menschen' can not be ascertained. Schiller's dissertation had been rejected on the grounds that it did not adhere strictly enough to the established medical authorities in the field.

The requirement that all medical students remain at the Karlsschule for yet another year was caused by the fact that not all formalities with respect to the students' later medical practice had been worked out, yet. During that year, Schiller presumably read 'Fausts Leben' by Mueller, the novels of Christoph Martin Wieland, the writings of Rousseau and Montesquieu, Winckelmann's 'Geschichte der Kunst des Altertums' (Classical Art History), Lessing's 'Laokoon', as well as Herder's 'Auch eine Philosophie der Geschichte zur Bildung der Menschheit' (Yet Another Philosophy on the History of the Education of Mankind).

Under the influence of Daniel Schubart's poem, 'Fuerstengruft' (Prince's Tomb), which Schiller came to know in its original handwritten version, the poems 'Die Gruft der Koenige' and 'Triumphgesang der Hoelle' were written. Only fragments of them have survived.

A poem that the Duke had commissioned from Schiller in which the advantages of the Karlsschule over the Tuebingen University were to be praised, was rejected several times as not suitable.
