Brief History of Biliran Province In the early Spanish chronicles,istory in Biliran Biliran Island was known as Isla de Panamao, referring to its northernmost mountain which was an eruptive volcano described in the 1668 manuscripts of Jesuit Father Francisco Alcina. Other accounts also described the island as a shipyard during the Spanish period. The earliest written mention of the name Biliran Island was made around 1685, the name Biliran referring to a native grass called “boro-biliran” which abounds in the area. It was theorized that cataclysmic eruption of Mount Panamao in 1669 has prompted the change of name into Isla de Biliran, probably influenced by a folk belief of name-switching, which was supposed to appease the evil spirits believed to have caused the eruption.
