A Structural Classification of the Liber Linteus Using the Sigilith Framework

This study presents the first structural classification of the Liber Linteus Zagrabiensis, the longest surviving Etruscan manuscript. Rather than pursuing linguistic translation, the analysis applies the Sigilith framework—a symbolic systems methodology designed for ritual and procedural texts—to map the manuscript's internal architecture. Through segmentation analysis, formulaic pattern mapping, operator identification, and domain–phase modeling, the study reveals a twelve-domain structure organised into four macro-phases. These include foundational rites, transitional rituals, calendrical cycles, and funerary or end-cycle sequences. The findings demonstrate that the Liber Linteus operates as a coherent ritual-procedural system, offering a new foundation for interdisciplinary research into symbolic manuscripts.
