Five seeing and seven blind
give us twelve, in all, we find;
but all of these, ’tis very plain,
come into account again.
For take notice, it may be true,
that those blind of one eye are blind for two
and consider contrariwise,
that to see with your eye you may have your eyes.
So setting one against the other,
for a mathematician no great bother,
and working the sum, you will understand
that sixteen wise men still trouble the land.
