The present set of so far unpublished letters by Helena Modrzejewska, written mainly in English, makes predominantly a matter of lesser importance in the Polish actress’ epistolographical achievements. Nevertheless it can be proved that those apparently trivial letters form a significant record of Modrzejewska’s private life, and also take on a function of a material memento of the famous actress. Paradoxically, within the scope of their functional character that serve useful purpose, there are also the actress’ reflections about more intimate and existential matters as well as comments on the then political issues. A typological break is made by letters to a poet Henry W. Longfellow written originally in French. Shaped as an intimate diary in which the foreground is occupied by the writing subject and where communicative issues became blurred, the letters give a full image of Modrzejewska’s writing craft. Linear reading of the set of letters trigger the elements of narration which in turn transforms into a kind of Helena Modrzejewska’s biography.
