In 1980, the Italian publisher Einaudi wanted to publish a series of personal anthologies of its authors. Primo Levi quickly arose to the challenge and submitted La ricerca delle radici ( The Search for Roots ): thirty excerpts from thirty masterpieces of world literature, accompanied by thirty short introductions he wrote. Every such introduction is a brilliant commentary on the work, and a reflection of Primo Levi himself - as a kind of self-portrait, in which the painter produces his collage from materials created by others. These excepts - published for the first time in Hebrew - reveal some of the important ethical and aesthetic influences on Primo Levi and his work. Levi quotes from Job, Lucretius, Rabelais‏, Babel, Shalom Aleichem, de Saint-Exupéry and more, but also from Darwin's On Origin of Species and even from Practical Organic Chemistry. Thus, it is possible to trace his extensive and diverse, humanistic and scientific education, the roots from which his unique literary work grew.
