The wall of
the city is high and of a           colour, like unto the rainbow,
in which are four gates, though Homer speak but of two: for there are
two which look toward the fields of sloth, the one made of iron, the
other of potter's clay, through which those dreams have passage that
represent fearful, bloody, and cruel matters: the other two behold the
haven and the sea, of which the one is made of horn, the other of
ivory, which we went in at.
