It is not often that one comes across an ancient keris that has been preserved in top condition like this. Though the pamor motif is a little faded here and there, yet the ricikan are still clearly visible and remained pretty much intact. And for a straight-bladed keris (‘lurus‘), this dapur is elaborated with quite a lot of ricikan.
‘Wora-wari‘ is a general term for kerises with straight blades (‘keris lurus‘) featuring gusen and lis-lisan. However, Wora-wari often matches the same criteria of a dapur Sinom; and so, over the course of time, this particular dapur became generally known as ‘Sinom Wora-wari’.
One of the main characteristics of a dapur Sinom Wora-wari is that it usually features a rather thick blade. This may also explain how the blade could withstand the test of time. Moreover, if the estimation of its approximate age is correct, then this keris may be almost a thousand years old.
Next, the hilt is made in the renown style of Madura, East Java. This also corresponds to the geographical and historical context of the Kahuripan/Janggala era (10th–11th century CE) in which this keris was made. The Kahuripan Kingdom was established by Raja Airlangga (991–1049) after he had spent many years in solitary retreat in the forest.
Airlangga was born in Bali and later he further expanded his kingdom to East Java. Hence, the meaning of the name Airlangga: ‘He Who Crossed the Water‘. King Airlangga was known as a tolerant ruler and an active supporter of Hindu-Buddhist traditions as well as art and material culture.
