   {Gom(822c)} is the papyrus, so famous in all antiquity.  It grows
   on the banks of the Nile, and in marshy grounds; the stalk
   rises to the height of six or seven cubits above the water,
   is triangular, and terminates in a crown of small filaments,
   resembling hair.  This reed was of the greatest use to the
   Egyptians; the pith serving them for food, and the woody part
   to build vessels with; which vessels frequently appear on
   various monuments of Egyptian antiquity.  That boats were
   made of this reed is also attested by Pliny and others.
