These range from more subtle observations on aesthetics, such as the discussion of how Goethes command of the formal qualities of the seven lengthy poems making up the seminal, pre-Islamic Arabic collection of the Moallakat
(Mu'allaqat) later influenced the Divan, particularly in his emulation of motifs known as nasib.

, whose German translation and introduction by Anton Theodor Hartmann was the source of inspiration for Goethe's writing the poem "Hegira" (79-93).
Thus Katharina Mommsen' Goethe und die Moallakat
(Berlin: Akademie-Verlag, 1960) is criticized for relating the poet's response to Anton Theodor Hartmann and ignoring his knowledge of William Jones's scholarly work.
