In the Persian epic poem Amir Arsalan, what kind of weapon is Shamshir-e Zomorrodnegār?
Amir Arsalan Amir Arsalan-e Namdar (Persian: امیر ارسلان نامدار‎ ‎ ) is a popular Persian epic, which was told to Nasser al-Din Shah Qajar, the Qajar Shah of Persia in the 19th century (though the Persian legend itself is much older), by a storyteller named "Mohammad Ali Naqib al-Mamalek" (Persian: میرزا محمدعلی نقیب‌الممالک‎ ‎ ). Mohammad never transcribed the poem himself, but the daughter of the Shah—who also loved the story—eventually transcribed it and preserved it for history.
Urumi The urumi (Malayalam: ഉറുമി, "urumi"; Tamil: உறுமி, "urumi", Sinhalese: එතුණු කඩුව "ethunu kaduwa"; Hindi: "āra") is a sword with a flexible whip-like blade from the Indian subcontinent. Originating in what are now southern India and Sri Lanka, it is thought to have existed as far back as the Maurya Empire. It is considered one of the most difficult weapons to master due to the risk of injuring oneself. It is treated as a steel whip, and therefore requires prior knowledge of that weapon as well as the sword. For this reason, the urumi is always taught last in Indian martial arts.
