Baybayin
Baybayin is a script which was used in the Middle Ages on the island of Luzon (today part of the Philippines). It is a syllabic script. Baybayin was used for Tagalog, Ilocano, and Pangasinan. It had already been in use in the 12th century, and was widely used before the Spanish colonial era (which started in the late 16th century). Baybayin is an abugida - every letter is a consonant. Spanish misssionaries used Baybayin to spread the Christian faith. The book Doctrina Christiana, en lengua española y tagala was one of the first Christian books printed, in 1592. The book is written in Tagalog, using Baybayin, and Spanish, using the Latin alphabet.
