ABSTRACT
The present chapter originates from curiosity stimulated by a letter that Piero Sraffa wrote to John Eatwell and Alessandro Roncaglia in 1974. Eatwell and Roncaglia had been working on an English translation of Piero Sraffa’s 1925 Annali article (Sraffa 1925a). They had had endless sessions with him, discussing the details of the translation. When everything was finished and the article was ready for publication, Sraffa had second thoughts and wrote them a letter, in which he withdrew, at least temporarily, his permission to publish.
