Lanao is the subject of various myths and legends. It supports a major fishery, and powers the hydroelectric plant installed on it; the Agus River system generates 70% of the electricity used by the people of Mindanao. A commanding view of the lake is offered by Marawi City, the provincial capital. Visual arts Sarimanok, Papanok a "Məra" or "Marapatik" is a legendary bird of the Maranao that is a ubiquitous symbol of their art. It is depicted as a Hoodhud (Arabic) with colorful wings and feathered tail, holding a fish on its beak or talons. The head of Sarimanok is like the head of a Hoopoe (Balalatoc in maranaw) and is profusely decorated with scroll, leaf and spiral motifs (okir). It is a symbol of good fortune. The Maranao have also developed their own adaptation of the Ramayana epic, the Maharadia Lawana. They also have a traditional dance, the Singkil, which was based on another local Ramayana adaptation, the Darangən. Architecture Traditional Maranao architecture, like elsewhere in the Philippines and at large maritime Southeast Asia, follows the Austronesian framework of wooden structures on piles, divided in three tiers pertaining to social class:torogan of royalty, mala a walay of lesser nobility, and the common lawig analogous to the bahay kubo. Music and performing arts Maranao kulintang music is a type of a gong music. Sarunaay is also found among both Muslim and non-Muslim groups of the Southern Philippines. Kobbing is a Maranao instrument and Biyula is another popular Instrument. Biyula is a string instrument. In 2005, the Darangen Epic of the Maranao people of Lake Lanao was selected by UNESCO as a Masterpiece of the Oral and Intangible Heritage of Humanity. Cuisine Maranao cuisine is spicier compared to most regions elsewhere in the Philippines, a trait largely shared with much of Mindanao. Traditionally cultivated spices, locally known as palapa (Bontang, native product of Gandamatu) are a common condiment. It is made of stewed sakurab scallion bulbs, ginger, and chillies in coconut oil. Dishes are intertwined with important cultural rituals across all aspects of Maranao culture: from birth to death. Social structure Traditionally, Maranao society is divided into two strata. Namely, mapiyatao (pure) and kasilidan (mixed blood). kasilidan is further subdivided into categories which are as follows; sarowang (non-Maranao), balbal (beast), dagamot (Sorcerer/Sorceress) and bisaya (Slave). The mapiyatao are natives entitled to ascend to thrones by pure royal bloodline. On the other
