Bâlaybalan باليبلن

[jan_Sonja]

1. the world’s oldest grammatically complete conlang (14th–16th century)
2. seems to have been used for religious purposes, poetry, and facilitating understanding between secret societies
3. there is a tiny discord server dedicated to translating the documentation to English

That is so cool ! Have they published anything outside of the server ? Where was it used and developed ?

It was used in Western Asia and the Islamic world. It doesn’t seem clear who the designer of Bâlaybalan is. It looks like it was a community project.

There are some Reddit posts like: https://www.reddit.com/r/conlangs/comments/1aqyn7p/a_valentines_message_in_bâlaybalan_the_worlds/

A sample from the original dictionary of Balaybalan in Ottoman Turkish:

Correction: My teacher Żāmar informs me that “the collective endeavour was almost certainly headed up by Muhyî-i Gülşenî, as his name is included in the title of the language.”
