Under the frown of Couthon, one of the most atrocious colleagues of Robespierre, this early publication seems to have been so effectually suppressed that no copy bearing that date, 1793, can be found in France or elsewhere. In Paine’s letter to Samuel Adams, printed in the present volume, he says that he had it translated into French, to stay the progress of atheism, and that he endangered his life “by opposing atheism.” The time indicated by Lanthenas as that in which he submitted the work to Couthon would appear to be the latter part of March, 1793, the fury against the priesthood having reached its climax in the decrees against them of March 19 and 26. If the moral deformity of Couthon, even greater than that of his body, be remembered, and the readiness with which death was inflicted for the most theoretical opinion not approved by the “Mountain,” it will appear probable that the offence given Couthon by Paine’s book involved danger to him and his translator. On May 31, when the Girondins were accused, the name of Lanthenas was included, and he barely escaped; and on the same day Danton persuaded Paine not to appear in the Convention, as his life might be in danger. Whether this was because of the “Age of Reason,” with its fling at the “Goddess Nature” or not, the statements of author and translator are harmonized by the fact that Paine prepared the manuscript, with considerable additions and changes, for publication in English, as he has stated in the Preface to Part II. A comparison of the French and English versions, sentence by sentence, proved to me that the translation sent by Lanthenas to Merlin de Thionville in 1794 is the same as that he sent to Couthon in 1793. This discovery was the means of recovering several interesting sentences of the original work. I have given as footnotes translations of such clauses and phrases of the French work as appeared to be important. Those familiar with the translations of Lanthenas need not be reminded that he was too much of a literalist to depart from the manuscript before him, and indeed he did not even venture to alter it in an instance (presently considered) where it was obviously needed. Nor would Lanthenas have omitted any of the paragraphs lacking in his translation. This original work was divided into seventeen chapters, and these I have restored, translating their headings into English. The “Age of Reason” is thus for the first time given to the world with nearly its original completeness.
