The Ramakien, “Glory of Rama”, is Thailand’s national epic, derived from the Hindu epic Ramayana, and represents the battle between good and evil.
There are beautiful statues, sculptures, and paintings of Ramakien at many of the Thai temples. The wall painting pictured here is at Wat Pho.
Rather than repeat the story of The Ramakien here, I’m including the Wikipedia link below.
