Sunto
By studying the higher order focal properties of a family of linear spaces naturally associated to the singular locus of the theta divisor of a non-hyperelliptic jacobian of genus $g \ge 5$, we give a new proof of the classical theorem of Torelli. Related questions and open problems are also discussed.
