Tagbanwa

The Tagbanwa alphabet is one of a number of closely related scripts used in the Philippines until the 17th Century AD. It is thought to have descended from the Kawi script of Java, Bali and Sumatra, which in turn descended from the Pallava script, one of the southern Indian scripts derived from Brahmi.
