Dr. Brandes, observing that the _chandi_ Boro Budoor must have been meant because there is no other place known of the same name and its strategical value, given ancient modes of warfare, is obvious, puts the date of its investment by Pangeran Pringgalaya to seize Ki Mas Dana, at 1709 or 1710. A native reference to the Boro Budoor of half a century later, is found in a Javanese manuscript, used by Professor C. Poensen for a paper on Mangku Bumi, first Sooltan of Jogjakarta.[167] The conduct of the Pangeran Adipati, son of that Sooltan, grieved his father very much. Besides his ignorance in literary matters, he was proud and arrogant; he disdained his father’s advice and associated with the women of the toll-gate, which caused all sorts of annoyance. He went also to the Boro Budoor to see the thousand statues, notwithstanding an old prediction that misfortune would befall the prince who beheld those images, for one of them represented a _satrya_ (a noble knight) imprisoned in a cage; but it was the Prince’s fate that he wished to see the statue of the _satrya_. Having gratified his desire, he remained in the Kadu, where he led a most dissolute life. This gave great sorrow to his father, the Sooltan, because the scandal reached such dimensions that the (Dutch) Governor at Samarang heard of it and reprimanded him. Ashamed and angry, he sent a few _bupatis_ with armed men to order the Pangeran Adipati to return to Ngajogja (Jogjakarta); if he refused, they had to use violence and were even authorised to kill him. The Pangeran Adipati obeyed and was kindly received by his father, but soon after he fell ill, spat blood and died. A letter of the Governor-General J. Mossel, dated December 30, 1758,[168] contains the passage: “His Highness’ eldest son, the pangerang Adipatty Hamancoenagara, having departed this life, ...” and the profligate Crown Prince’s visit to the Boro Budoor may therefore be put at a few years less than fifty after Ki Mas Dana’s rebellion.
