By chance I stumbled on a Wikipedia article about Allah Jang Palsoe, an Indonesian stage play, dating from 1919, by Kwee Tek Hoay. The title translates as False God and is about two brothers who discover that money does not bring happiness.
Despite the fact that the original idea came from a short story by E. Phillips Oppenheim, a westerner, it is a truly Indonesian work and is still sometimes performed.
Reading the article I realised I know practically nothing about Indonesian theatre, or other literature. I have heard of the puppet theatre and have even seen extracts on TV, but that’s the extent of my knowledge. I strongly suspect that Indonesians know much more about our theatre than we do about theirs: they may even read Shakespeare in school.
My ignorance probably extends to numerous theatrical traditions, and it seems such a pity to miss so much. Another topic to add to my ‘to be googled’ list.
