Maogamalcha
Maogamalcha was a place in Mesopotamia, attacked and taken by the Roman Emperor Julian ( Ammianus Marcellinus xxiv. 4.). It appears to have been strongly fortified and well defended. Zosimus evidently alludes to the same place, though he does not mention it by name, and states it was about 90 stadia from Ctesiphon (Zosimus iii.21).
