Could some of those quivers also carry the bow?  The curving shapes suggest the potential.  But in all the illustrations I've seen, the bow is in use. I have seen a few drawings that showed the archers with the bows slung over the shoulder.  But this seems too dangerous of a way to transport a valuable instrument.  On closer inspection... Are some quivers and others bow cases?
