This 1984 two-volume magnum opus by Thomas V. Gamkrelidze and Vyacheslav V. Ivanov is a landmark achievement in historical linguistics and one of the most significant works of 20th-century Soviet science. Presented with a preface by the renowned linguist Roman Jakobson, this monumental study offers a comprehensive reconstruction of the Proto-Indo-European language and a detailed analysis of the culture of its speakers. The work is celebrated for its groundbreaking "glottalic theory," which revised traditional views on the Proto-Indo-European consonant system, and for its extensive semantic dictionary. Published by Tbilisi University Press in an encyclopedic format with a substantial print run of 5,000 copies, this set represents the culmination of decades of research and established its authors as leading global authorities in the field. It is an indispensable reference for linguists, historians, and anthropologists worldwide.
