Chilanum are all over the age spectrum. See https://commons.wikimedia.org/wiki/...anum?uselang=de
Take the first example at the web page above. This one is 1500/1600 vintage.
there is an 18th C example.
As a general note not limited to this weapon only~ There are many people who may not know what a Chilanum is... or that it is also called a Chilanam, where it is from or anything else about it.
Technology is roaring away at a pace...
Is there not a simple program that can do Forum a few favours like automatically list the top 5 threads at Forum Library concerning this or that weapon ? and place those at the beginning of every thread ?
Algorithyms can sort Library references in about a half a second...?
