Today next concept art for Nubians. It's Nubian infantry. This is the most heaviest type of infantry which have Nubians. These troops have medium length spears for fighting in free space and against cavalry and short Nubian swords for close fighting; have leather shields, quilted armour and iron helmets with quilted aventail for protection. Since the issue of helmets remains open, the helmets are 100% hypothetical. Short swords with a sash over shoulder can be seen on medieval Nubian paintings. Quilted armor presumably have warriors from the Crucifixion scene from Faras' Cathedral. Swords and helmets also mentions by Ibn Hawqal as weapons of al-aḥadiyyūn in his book Kitab Ṣūrat al-arḍ (about 977 A.D.):
As well Nasir i-Khusraw (about 1050 A.D.) reports interesting information:
The 1st, 2nd and 3rd images represents the same type of warrior. The 1st warrior bear the sword in Nubian style - on the sash over the left shoulder, and 2nd warrior fixed his sword's scabbard by belt in Meroitic style.
The 3rd is bannerbearer. The banner is 100% hypotetical. It represent the monogram of St. Archangel Michael (one of the known in Nubia). Earthly Christian Nubian army appeal to the Chief of Heavenly Army for protection.
