W. J. Schelling's 1842 lectures on the Philosophy of Mythology are an early example of interdisciplinary thinking. In seeking to show the development of the concept of the divine Godhead in and through various mythological systems (particularly of ancient Greece, Egypt, and the Near East), Schelling develops the idea that many philosophical concepts are born of religious-mythological notions. In so doing, he brings together the essential relatedness of the development of philosophical systems, human language, history, ancient art forms, and religious thought. Along the way, he engages in analyses of modern philosophical views about the origins of philosophy's conceptual abstractions, as well as literary and philological analyses of ancient literature and poetry.
