Keris Djogya?

[A. G. Maisey]

The dress is certainly Jogja, I'm away from my references at the moment so I cannot give the wanda of the hilt.

The wood in the wrongko is definitely not burl teak (jati gembol). I cannot ID it from the photos, but it is a low quality material.

The pendok motif might be an alas-alasan one, but there are insufficient detailed photos for me to give an opinion.

I need to get on to a decent computer & monitor to comment on the mendak.

The blade has the pawakan --- overall visual impression --- of a typical Jogja blade, but if I look at details it has a hint of Madura. Possibly this Madura impression might come from photo distortion --- angles --- I'd need to handle it to be certain.

I reckon 99.9% of keris literate people would place this keris, including blade, slap dab in the middle of Jogja.

That name "Jogja" is interesting.
This city is named after Ayodhya, the place where Rama (of Ramayana fame) was born, in Jawa this became Ngayogyakarta, sometimes pronounced Ngayogyokerto or Ngayodyokerto, & commonly abbreviated to Ngayogyo/Ngayodyo until today.

The official spelling is Yogyakarta, abbreviated to Yogya or just Yog.

The spelling of all variations of the name of this city can vary, both as to vowels & consonants, this is just one of the idiosyncrasies resulting from the fact that Javanese is not a standardised language.
