The Pararaton says a smith cursed the kris that killed him, and that it killed three rulers of Singhasari in turn

The Pararaton is a Javanese chronicle whose surviving manuscript was written after 1481; scholars treat its account of Ken Angrok (Ken Arok) as legend. It says Ken Angrok ordered a kris from the smith Mpu Gandring of Lulumbang and demanded it in five months. The smith said a proper blade needed a year. When Ken Angrok came back and found it unfinished, he stabbed the smith with it. The dying smith said: the kris will kill you, your children and grandchildren, and seven kings will die by it. Ken Angrok lent the kris to Kebo Hijo, who wore it every day, then used it to kill Tunggul Ametung, ruler of Tumapel. The town blamed Kebo Hijo. Ken Angrok married the widow, Ken Dedes, and became king. Her son Anusapati, Tunggul Ametung's child, learned who had killed his father, asked his mother for the kris, and had a man from Batil stab Ken Angrok at dinner. The chronicle dates his death to Saka 1169 (1247). Ken Angrok's son Tohjaya borrowed the kris from Anusapati and stabbed him during a cockfight; the Pararaton dates it Saka 1171 (1249). A statue of Prajnaparamita found near Singhasari, which local tradition links to Ken Dedes, was taken to Leiden in 1820 and returned to Indonesia in January 1978. It is in the National Museum in Jakarta.
