 In 1830 Humboldt edited and published his correspondence with the poet Schiller and included a lengthy essay “On Schiller and the Path of his Intellectual Development” (“Ueber Schiller und den Gang seiner Geistesentwicklung”, GS Vol 6: 492–527). In the same year appeared also an extensive essay on the late Goethe in the form of a review of the concluding part of the poet’s Italian Journey that had been published the previous year. There he attempted, as he had done before in his Schiller essay, to interpret the various sides of the poet from one central point of view: this time from the poet’s perception of art and nature (“Rezension von Goethes Zweitem römischen Aufenthalt”, GS Vol 6: 528–550). During the remainder of his life most of his time and energy was spent on what was to be his magnum opus: a monumental study of the Kavi Language on the island of Java within the context of the entire Austronesian language group of the Pacific.
