Upon the reading of his death warrant, he supposedly remarked, "I see that you have made three spelling mistakes."[4] However, this version appears to derive from a five act play Marion de Lorme by Victor Hugo, written in 1828 and performed in 1831.[5] Ferdinand Rothschild gives the quotation as "Permit me to point out that you have made three mistakes in spelling".[6] One source says merely that "Favras then quietly corrects the spelling and punctuation errors made by the clerk in his statement".[7]
