And the shapes of the locusts were like unto horses prepared unto battle; and on their heads were as it were crowns like gold, and their faces were as the faces of men. The locusts were like unto horses - This description of the locusts appears to be taken from Joel 2:4. The whole of this symbolical description of an overwhelming military force agrees very well with the troops of Mohammed. The Arabs are the most expert horsemen in the world: they live so much on horseback that the horse and his rider seem to make but one animal. The Romans also were eminent for their cavalry.
Crowns like gold - Not only alluding to their costly tiaras or turbans, but to the extent of their conquests and the multitude of powers which they subdued.
Their faces were as the faces of men - That is, though locusts symbolically, they are really men.
