Lines of breathless length

Brief reflections on definitions of LINE . . .

          Breathless length     by JoAnne Growney

          A LINE, said Euclid, lies evenly
          with the points on itself --
          that is, it’s straight –-
          and Euclid did (as do my friends)
          named points as its two ends.

          The LINE of modern geometry
          escapes these limits
          and stretches to infinity.
          Just as unbounded lines
          of poetry.
