The concept nearby fundamental group is introduced and we develop a theory of iterated integrals along elements of this group. We give an example for which the MHS on the nearby fundamental group detects a modulus which is invisible for the MHS on the vanishing cohomology.75 pages, LaTeX2e; the same paper!
