Charles Francois Dupuis was born near Chaumont, in France, the 16th Oct, 1742, died 29th Sept, 1809. He played a prominent part in the great revolutionary movement, and was Secretary to the National Convention. His famous work, “L’Origine de tous les Cultes,” is one of the grand heresy marks of the eighteenth century. Himself a Pantheist, he searched through the mythic traditions of the Greeks, the Egyptians, the Hindus, and the Hebrews, and as a result, sought to demonstrate a common origin for all religions. Dr. John Pye Smith classes Dupuis as an Atheist, but this is most certainly an incorrect classification. He did not believe in creation, nor could he go outside the universe to search for its cause, but he regarded God as _“la force universelle et eternellement active,_ ” which permeated and animated everything. Dupuis was an example of a new and rapidly increasing class of Freethinking writers—i.e., those who, not content with doubting the divine origin of the religions they attacked, sought to explain the source and progress of the various systems. He urges that all religions find their base in the attempts at personification of some one or other, or of the whole of the forces of the universe, and shows what an important part the sun and moon have been made to play in the Egyptian, Greek, and Hindu mythologies. He argues that the fabulous biographies of Hercules, Bacchus, Osiris, Mithra, and Jesus, find their common origin in the sun-worship, thus cloaked and hidden from the vulgar in each country. He does not attack the Hebrew Records as simply inaccurate, but endeavors to show clear Sabaistic foundation for many of the most important narratives. The works of Dupuis and Dulaure should be read together; they contain the most complete amongst the many attempts to trace out the common origins of the various mythologies of the world. In the ninth chapter of Dupuis’ great work, he deals with the “fable made upon the sun adored under the name of Christ,” “_un dieu qui ait mangé autrefois sur la terre, et qu’on y mange aujourd’hui_” and unquestionably urges strange points of coincidence. It is only astrologically that the 25th of December can be fixed, he argues, as the birthday of Mithra and of Jesus, then born of the celestial Virgin. Our Easter festivities for the resurrection of Jesus are but another form of the more ancient rejoicing at that season for Adonis, the sun-God, restored to the world after his descent into the lower regions. He recalls that the ancient Druidic worship recognised the Virgin suckling the child, and gathers together many illustrations favorable to his theory. Here we do no more than point out that while reason was rapidly releasing itself from priestly thraldom, heretics were not content to deny the divine origin of Christianity, but sought to trace its mundane or celestial source, and strip it of its fabulous plumage.
