For thirty-five years a major scholarly dialogue, (which often spilled over into abrasive debate) has enlivened the study of comparative Indo-European religions and mythology. At the center of this academic storm is Georges Dumézil, whose brilliant insights into the nature of early Indo-European cosmology, myths, rites, deities and social structure, have sent dozens of historians of religion, philologists and linguists to the texts in efforts to either corroborate or disprove his theories. The extent of Dumézil's influence may be seen in the number of scholars who have developed and amplified his ideas in their own research. Another, equally significant measure of his influence may be found in the number of well-informed critics which the French scholar has attracted. Dumézil's central theory, concerning the tripartite ideology of the Indo-Europeans, has proven to be suggestive and stimulating for scholars in Germanic, Roman, Celtic, Scandinavian and Indie studies. Certainly, Dumézil ranks alongside other great contemporary French scholars such as Braudel and Lévi-Strauss. Like them, his work has had an incalculable effect upon his discipline and upon the world of scholarship.
