174 517 was the registration number imprinted on his skin, an indelible mark that brands the deportee and annihilates the person. Not an accidental number and highly symbolic: Primo Levi travelled on carriage number 174 and was the five hundred and seventeenth man who got off that train. It was February 26, 1944, when he entered the door of an unimaginable hell.

The graphic novel by Franco Portinari and Giovanna Carbone traces Primo Levi's footsteps, from his deportation to Auschwitz until his return home.

A story that finds new life in the form of illustration and deserves, now more than ever, a careful re-reading to remember and not to allow the horror to repeat itself.
