The lines that mathematics draw
(angular circumscription of 
the curved impatience of a paw;
the eccentric swell of love)
define but cannot rule at all 
the leaping inward animal.

The leaping inward animal
(the satyr in his lonely wood,
the lamb in his Wordsworthian dale)
makes every leap a maidenhead;
nor can the printed place foresee
where next those lusty feet may lie.

Where next those lusty feet may lie
(in pitfalls for the grinning wolf
or by the writhing iron sea)
is a great sickness in itself
whose large enfevered motions flaw
the lines that mathematics draw.
