Divergence
The Javanese Ramayana differs markedly from the original Hindu prototype. The first half of this Ramayana Jawa is similar to the original Sanskrit version, while the latter half is divergent to the point of being unrecognizable by Indian scholars of the original Ramayana. One of the many major changes is the inclusion of the all-powerful Javanese indigenous deity dhayana Guardian God of Java Semar (in Balinese literature known as Twalen) and his misshapen sons, Gareng, Petruk, and Bagong who make up the numerically significant four Punokawan or "clown servants". This latter, altered half of the original tale is the most popular, and it is performed in all wayang performances.
