As John these stones named in his book,
I knew the names, as he doth tell.
Jasper hight the first gem there,
that on the first base I discern'd;
on lowest course it glisten'd green;
sapphire held the second step;
the chalcedony then, without a spot
on tier the third shone pale and pure;
the emerald fourth, so green of scale;
the fifth stone was the sardonyx;
the sardius sixth; in Apocalypse
John the Apostle discern'd it then.
