"I was a chemist in a chemical plant... and I stole in order to eat. If you do not begin as a child, learning how to steal is not easy; it had taken me several months before I could repress the moral commandments and acquired the necessary techniques... I stole everything except the bread of my companions. ...There was a mysterious jar ...It contained ...gray, hard, colorless, odorless, tasteless little rods and did not have a label ...[T]he Russians were a few kilometers away ..; everybody knew the war was about to end: but finally some constants must still subsist, and among them were our hunger ...Alberto took a penknife ...He tried to scrape it ...and saw a spray of yellow sparks ...it was iron-cerium ...from which common flints of cigarette lighters are made. ...Alberto ...explained ...they were mounted on the tips of oxyacetylene torches to ignite the flame. ...Alberto ...did not accept the concentration camp universe ...and miraculously he had remained free ...he had not bowed his head ...I has stolen the : good ...he would turn it into ...an article of high commercial value. Prometheus had been foolish to bestow fire... instead of selling it... the price of a lighter flint was equivalent to a ration of bread... one day of life. ...[I]n two months cerium would have liberated us, an element about which I knew nothing, save ...that it belongs to the equivocal and heretical rare-earth ...family, and that its name has nothing to do with the ...word for wax (cera) and ...it celebrates ...the asteroid Ceres, since the metal and the star were discovered in the same year ...an affectionate-ironic homage to alchemical couplings: just as the Sun was gold and Mars iron, so Ceres must be cerium."
