When the Iranian Shahnameh hero Rostam would have fought in a dual against Frisian freedom fighter Pier Gerlofs Donia who would have probably won?

Answer 1

Rostam and Pier lived in different times, different cultures and among different people; there is now way they couldm have met each other. If they did, it would have been one hell of a sight! You should not forget, however; Rostam was a hero, and Donia was just a man driven insane by the killing of his intire family. A man who fights demons and wizards in ancient times, shouldn't have much problems defeating a slow brute. So the fight would likely go something like this:

Rostam walks towards his enemy, who is an awfully large brute, and takes his sword without even the slightest fear or regret. Before Donia can even grab his 2,15 meter sword, Rostam stands in front of him, stabbing him in the upper leg or abdomen with his own. By then, Donia would have wielded the gigantic sword, but due the pain of the wound inflicted, his strike likely misses his opponent. Than, Rostam cuts the enormous hand of Donia, and the giant drops his sword. After this, Rostam would have stabbed the giant in the chest, finishing him of. That's my opinion.
