The parang, or sword motif of Central Java was traditionally meant to be worn only by the royal family. The pattern was designed to signify power, but the highly regarded Winotosastro batik makers say that the parang rusak motif also displayed the triumph of wisdom and nobility over earthly desires.
One will find many, many versions of parang pattern from small to large, but I like the feel of the large patterned piece from Cirebon, (pictured here). It looks great as a hanging panel.
Large or small, the parang rusak will always have the continuous wavy pattern, always on the diagonal. See another example of batik rusak from the Australian Museum collection.
