The document discusses the Box-Headed script, which was used in India from the 4th to 7th centuries AD. This script featured letters with small square or rectangular "boxes" on the tops. It originated in the Gupta period and was used by dynasties like the Vakatakas, Sarabhapuriyas, Nalas, Kadambas, and Panduvamsis in their official records. The script developed regionally before disappearing after the 7th century. It represented an artistic development of serifs in letterforms during this period in central and southern India.
