'Alle menschliche Gebrechen/Sühnet reine Menschlichkeit'

‘Alle menschliche Gebrechen/Sühnet reine Menschlichkeit’, closing lines of an 8-line dedicatory poem written by Goethe on the fly-leaf of a copy of Iphigenie auf Tauris, which he gave to the Berlin (and former Weimar) actor Georg Wilhelm Krüger (1791-1841) on 31 March 1827. It is often quoted as an apt poetic summing-up of Iphigenie by its author. The superscription, which the poem bears in Goethe's collected works, is Dem Schauspieler Krüger mit einem Exemplar der ‘Iphigenie’.
