Tom, the authors did not specify from whence they got this information, though I noted a book in the biblography called "Arms&Armor in Spain Vol.1" by A.B. de Hoffmeyer. Also among the bibl. is "Hannibal & the Enemies of Rome" by Peter Connolly along with "Histories" by Polybius, "The War With Hannibal" by Livy, and "Makers of Rome" by Plutarch. There are a few others, though from the titles, they wouldn't appear to be the source. Here's another thought: What if this design of weapon did not originate in Greece or North Africa and spread to Nepal via Alexander? What if came to the region of India via the Indo-Europeans who carried it in from somewhere in the steppes? Following waves of Indo-Europeans may have then carried it to Greece (perhaps the Hyksos introduced the idea to the Egyptians earlier than that if one would think the Hyksos to be of Indo-Aryan stock.) R. Gordon Wasson advanced the theory in his book "Soma: The Divine Mushroom" that the Soma spoken of in the Rig Veda was the Amanita Muscaria (Fly Agaric) and that this was introduced by the Indo-European conquerers of the region from their point of origin; perhaps the coniferous forests bordering the steppes. This mushroom is mycorrhizal; it needs to grow among conifers which are its symbiotic host. So if Wasson's theory is correct, and this mushroom is Soma, this means that other things as well as this mushroom may have traveled along with it. Perhaps this puts the point of origin for the weapon somewhere in Asia, I would say close to Siberia (where shamanic use of Amanita Muscaria still continues.) It would appear to me that a slashing weapon such as this would be extremely effective from a speeding chariot running down infantry. The early Indo-Europeans were probably the fathers of chariot warfare, conquering as they went with their superior weaponry. Tom, what do you think about this? It's reaching far, but I wonder if this style of weapon came to the regions it was (and is) in from a different direction.
