Thank you so much Olikara for posting this outstanding, detailed, and most certainly pertinant information that indeed does apply a great deal in the study of weapons! It really is great to see you posting again, recalling the fascinating Tipu Sultan hilt you posted a short time ago.
In the study of weapons, nusimatics is often key in identification processes, not only in terms of the representations seen in the iconography, but in some cases in symbolism and marking comparison. Since coins are in many cases of course dated either numerically or by the regalia or figures represented, this can help often chronologically in identifying weapons. Naturally a degree of caution applies, however using this factor will often present reasonable benchmarks.
The information you have provided is most helpful in our study of the weapons of India, particularly those of the Hindu culture, which have at last become somewhat more understandable thanks to the outstanding work of Dr. Robert Elgood in his "Hindu Arms and Ritual". He has made it clear that the study of these weapons requires the understanding of the culture, religion, and symbolism inbued in them, and keenly corroborates exactly what you have so well placed here.
Outstanding post!!! Thank you so much
All very best regards,
Jim
