"Le Périgord" the poem which is discussed in detail Stone heart, written on the occasion of a visit by Paul Celan in August 1964 Baneuil Castle, in Périgord. This is the testimony of an encounter, difficult and fruitful, between those who had "come from away" as the poem, distant and unhappy Bucovina, Romanian old, Ukraine today, and an old country of southern civilization says, of hills, vineyards, castles and fields of snuff. An old country marked, in the eyes of the poet, for the stay of Hölderlin in 1802. In "Le Périgord" is not difficult to hear a voluntary echo "Andenken" Hölderlin, composed in honor of this region; although it is, indeed, a critical echo, as it inevitably Celan associated with German culture Heimat, which has also inevitably turn to Heidegger.

Jean Bollack exposed to the attention of the friend ( "Le Périgord" is dedicated to his wife and him) and philologist different strata hermeneutics draws from each of the word-metaphor, words-words, words-crystal Celan , dark condensates experience. "The past in which the origin of the destruction of the Jews is rooted reads the oaks and the" stone ", and the above Twinkling Star" Bollack writes. This ode allows us to attend, then to the transfiguration of the familiar landscape of Périgord in "Peri-gord" ( "stone heart"), where the poet always wears mourning of the dead in the fields of concentación "Singing It is imported into a country of sun, but remains marked by mourning. The scorched earth takes an ashen. "

In this book the information of a personal nature are intertwined with both attributed to Jean Bollack as Peter Szondi philological method. A method that is not content with generalities about the human condition, but dedicated aa point out the importance of biographical allusions or circumstances, often considered the "outside" the text: "The understanding of" hermeneutics "lies within the meaning of that continuity, writing a single text or "book" is rewritten and made explicit from within, from a poem to another. "

The original French edition of Stone Heart appeared in 1991. In that edition to the present Spanish text has considerably increased, the result of joint work of the translator, Arnau Pons, with Jean Bollack own. Collaboration that can be said is born a new book.
