Linguist deciphers mysterious 2,400-year-old Dhofari script

Linguist Ahmad Al-Jallad from Ohio State University has successfully deciphered the main subtype of the Dhofari script, a mysterious 2,400-year-old writing system found in Oman's caves and dried riverbeds, by identifying three abecedaries following the halḥam order characteristic of South Arabian scripts, revealing unexpected connections to northern Arabian writing systems rather than local southern Arabian ones.

The Halḥam Alphabetic Order

The breakthrough in deciphering the Dhofari script came when Al-Jallad identified three abecedaries—ancient alphabetic sequences similar to our ABCs—that followed the halḥam order characteristic of South Arabian scripts. Unlike the familiar Phoenician-derived alphabetic order (A-B-C), South Semitic languages organize their letters beginning with the sequence h-l-ḥ-m. This distinctive ordering system provided the crucial key to unlocking the script's mysteries.science+2

Al-Jallad's analysis began with an inscription from a Dhofar cave containing approximately 26 non-repeating glyphs, which he suspected represented an alphabetic listing rather than a sentence. His theory was confirmed when he discovered two additional inscriptions with identical sequences—one from another Dhofar cave and a third in a snake-like pattern from Duqm, Oman. By mapping these Dhofari glyphs to their equivalents in the halḥam system, Al-Jallad could finally assign phonetic values to the symbols, enabling the pronunciation and translation of words from this long-lost language.roger-pearse+2

Aramaic Influence on Dhofari

The decipherment of the Dhofari script has revealed fascinating connections to other ancient writing systems, particularly showing unexpected links to northern Arabian scripts rather than local southern Arabian ones. After examining the glyphs' shapes, Al-Jallad concluded they most likely descended from those used in Thamudic B, a script widely used in the northern Arabian Peninsula (modern-day Saudi Arabia's Najd province), suggesting a northward origin rather than a local evolution. This discovery challenges previous assumptions about the development of writing systems in the region and indicates complex patterns of cultural exchange across the Arabian Peninsula.leidenuniv.academia

The Dhofari script's northern connections highlight the historical importance of Aramaic influence on Arabian writing systems. Aramaic, a Northwest Semitic language first attested in the 12th century BCE, became a dominant administrative language across the Middle East and influenced numerous writing systems. The interchange between Aramaic and Arabic in pre-Islamic documents points toward widespread bilingualism, with contact between these languages stretching back centuries before the spread of Christianity in Arabia. This linguistic interaction helps explain characteristic features of early sedentary forms of Arabic, while conversely, contact with Arabic may explain distinctive features of western Aramaic dialects.roger-pearse+2

Ali Mahāsh al-Shahri's Documentation

The documentation of the Dhofari script took a significant turn in the early 1990s when Omani epigraphist Ali Mahāsh al-Shahri collaborated with British epigraphist Geraldine King to systematically record the painted inscriptions found in Dhofar's caves. Their meticulous work established that the Dhofari script comprised two distinct subtypes, which they classified as Script 1 and Script 2. Al-Jallad's recent breakthrough specifically deciphers Script 1, the more prevalent of these variants.science

Al-Shahri, now in his 70s, has dedicated much of his life to preserving and understanding the linguistic heritage of Dhofar. Honored with Oman's Order of Merit, First Class, for his contributions to Omani heritage and culture, he continues to document the endangered Shahri language (also known as Jibbali/Śḥərɛ̄́t), which belongs to the Modern South Arabian language family. His 2000 publication "The Language of Aad/لغة عاد" represents a valuable bilingual resource containing 210 proverbs, toponymy, traditional knowledge, and cultural practices of the region. Despite these efforts, al-Shahri has expressed concern that time is running out as elders with knowledge of these ancient linguistic traditions pass away, potentially taking irreplaceable cultural knowledge with them.zenodo+1

Recent updates in field of ancient scripts

Modern technology is revolutionizing the field of ancient script decipherment, with artificial intelligence emerging as a powerful tool for unlocking historical mysteries. AI applications now include optical character recognition for digitizing ancient texts, natural language processing for analyzing grammatical structures, and machine learning algorithms for pattern recognition in undeciphered scripts. This technological revolution has created a paradigm shift in decipherment speed and accuracy, helping researchers process vast archives of text previously considered too extensive for human analysis.repository.fit+1

The Indus Valley script remains one of the most tantalizing undeciphered writing systems, with recent approaches taking diverse paths toward cracking this ancient code. Researchers have developed specialized deep learning systems like ASR-net (Ancient Script Recognition), which can identify individual Indus symbols with 95% accuracy. Meanwhile, Tamil Nadu's government has offered a $1 million reward for successfully decoding the script, as competing theories propose it represents everything from a proto-Brahmi alphabet to a symbolic system rather than true writing. These developments, alongside MIT's algorithm for matching lost languages to known ones, demonstrate how the intersection of traditional scholarship and computational methods may finally unlock the secrets of humanity's most persistent linguistic puzzles.thefridaytimes+3
