Juan Abad was a Filipino printer, playwright, and journalist. His main contribution to Filipino theatre was his patriotic plays: the zarzuela Ang Tanikalang Guinto, and Isang Punglo ng Kaaway, the former which, caused his arrest and trial. Some authors credit Abad with the introduction of symbolism to Tagalog drama, a claim which is still to be proven; although he may have been one of the first Tagalog dramatists to use symbolism in their plays.
