early in 1745 mills and sellius published a prospectus for the "encyclopédie" to attract subscribers to the project. this four-page prospectus was illustrated by jean-michel papillon, and accompanied by a plan (see image), stating that the work would be published in five volumes from june 1746 until the end of 1748. the text was translated by mills and sellius, and it was corrected by an unnamed person, who appears to have been denis diderot.
