Wow, 'Nando,
What a fascinating interpretation!
Thank you so much for enlightening my dense mind!
I am not ashamed to admit that I did not include that option.
On the other hand, I know nothing on fishing.
I remember seeing records on the employment of incendiary arrows with matchlock muskets as late as the second half of the 16th c. though, the illustration of ca. 1570-80 probably of Spanish origin (attached) - a combination of devices which classic weaponry tends to confine to the earliest days of European firearms.
Well, you left me baffled if not flabbergasted.
Best,
Michl
