The Kharoshthi script, also known as ‘Gandhari’ script, is an ancient Indian writing system that emerged in the northwestern region of the Indian subcontinent (modern-day Pakistan and eastern Afghanistan) around the 4th century BCE. It was derived from the Aramaic script, which was the official administrative script of the Persian Achaemenid Empire that ruled over the Indus Valley region. The script was adapted to express the local Prakrit dialects, specifically Gandhari Prakrit.
Geographic Spread and Timeline
The script remained in active use from the 4th century BCE until its decline around the 4th century CE. It coexisted with the Brahmi script but was geographically confined to the northwestern frontier, extending along the Silk Road into Central Asia, including sites like Khotan and Niya in the Tarim Basin.
Epigraphic Prominence Under the Mauryan Empire
Ashokan Edicts and Language Adaptations
During the Mauryan Empire (c. 322–185 BCE), Emperor Ashoka utilized the Kharoshthi script to propagate his Dhamma (righteous path) in the northwestern provinces. While the vast majority of Ashokan edicts across the subcontinent were inscribed in the Brahmi script, the Major Rock Edicts in the northwest were carved in Kharoshthi to ensure accessibility for the local population. The underlying language used with this script was a regional variation of Prakrit.
Key Archaeological Sites of Mauryan Kharoshthi Edicts
The two primary locations of Ashokan Major Rock Edicts written in the Kharoshthi script are:
- Shahbazgarhi: Located in the Mardan District of Khyber Pakhtunkhwa, Pakistan. This site contains a record of all 14 Major Rock Edicts carved on a large quartz boulder.
- Mansehra: Located in the Mansehra District of Khyber Pakhtunkhwa, Pakistan. The edicts are inscribed across three large boulders, presenting the same code of civil and moral laws.
Paleographic and Structural Features
Direction of Writing and Typography
Unlike the Brahmi script (which is written from left to right and serves as the ancestor to most modern Indian scripts), Kharoshthi is written from right to left. This characteristic directly reflects its Semitic ancestry from the Aramaic alphabet.
Abugida Classification and Mechanics
Kharoshthi is classified as an abugida (a segmentary writing system), meaning that each character represents a consonant-vowel syllable.
- Consonants: The base character carries an inherent short ‘a’ vowel sound.
- Vowel Diacritics: Modifications or strokes added to the top, bottom, or sides of the consonant indicate alternative vowel sounds (i, u, e, o).
- Consonant Clusters: Long vowels and initial vowels are treated with distinct markers, though the script possesses a more limited system for marking long vowels compared to Brahmi.
- Lack of Distinct Word Separation: Inscriptions run continuously without clear spacing or punctuation marks between individual words.
Comparative Analysis: Kharoshthi vs. Brahmi Script
| Feature | Kharoshthi Script | Brahmi Script |
| Direction of Writing | Written from Right to Left | Written from Left to Right |
| Origin/Ancestry | Derived from the Aramaic script (Semitic origin) | Indigenously developed or influenced by Phoenician/Aramaic scripts |
| Geographic Zone | Restricted to the Northwest Subcontinent and Central Asia | Spread across the entire Indian Subcontinent and Southeast Asia |
| Mauryan Inscriptions | Used specifically in Shahbazgarhi and Mansehra Rock Edicts | Used in the majority of Rock Edicts, Pillar Edicts, and Minor Edicts |
| Evolutionary Legacy | Died out by the 4th Century CE; left no modern Indian descendants | Evolved into the Devanagari, Bengali, Tamil, Telugu, and other modern scripts |
| Visual Character | Features cursive, long, and angular brush-like strokes | Features geometric, rigid, and straight-line shapes |
Post-Mauryan Continuity and Final Decline
Adoption by Foreign Dynasties
Following the collapse of the Mauryan Empire, the Kharoshthi script maintained administrative and cultural relevance. It was extensively used by the Indo-Greeks, Indo-Scythians (Sakas), Indo-Parthians, and the Kushan Empire. Coins minted by Indo-Greek kings (such as Menander I) were typically bilingual, featuring Greek legends on the obverse and Kharoshthi Prakrit translations on the reverse.
Role in the Spread of Buddhism
Kharoshthi was instrumental in the early trans-regional transmission of Buddhism. The oldest surviving Buddhist manuscripts in the world—the Gandharan Buddhist Texts, dated between the 1st century BCE and the 3rd century CE—are written in the Kharoshthi script on birch-bark scrolls. These texts were carried by monks along trade routes into Central Asia and China.
Decipherment Trivia
The script was deciphered in the 19th century primarily by James Prinsep (who also deciphered Brahmi), Christian Lassen, and Charles Masson. They achieved this breakthrough by studying the bilingual legends on Indo-Greek coins, cross-referencing the known Greek royal names with their Kharoshthi equivalents.
