it publicly on 27 September in a lecture to the . On the same day he wrote the famous "" to Bon-Joseph Dacier, secretary of the Académie, detailing his discovery. In the postscript Champollion notes that similar phonetic characters seemed to occur in both Greek and Egyptian names, a hypothesis confirmed in 1823, when he identified the names of pharaohs Ramesses and Thutmose written in cartouches at Abu Simbel. These far older hieroglyphic inscriptions had been copied by Bankes and sent to Champollion by Jean-Nicolas Huyot. From this point, the stories of the Rosetta Stone and the decipherment of Egyptian hieroglyphs diverge, as Champollion drew on many other texts to develop an Ancient Egyptian grammar and a hieroglyphic dictionary which were published after his death in 1832. Later work Work on the stone now focused on fuller understanding of the texts and their contexts by comparing the three versions with one another. In 1824 Classical scholar Antoine-Jean Letronne promised to prepare a new literal translation of the Greek text for Champollion's use. Champollion in return promised an analysis of all the points at which the three texts seemed to differ. Following Champollion's sudden death in 1832, his draft of this analysis could not be found, and Letronne's work stalled. François Salvolini, Champollion's former student and assistant, died in 1838, and this analysis and other missing drafts were found among his papers. This discovery incidentally demonstrated that Salvolini's own publication on the stone, published in 1837, was plagiarism. Letronne was at last able to complete his commentary on the Greek text and his new French translation of it, which appeared in 1841. During the early 1850s, German Egyptologists Heinrich Brugsch and Max Uhlemann produced revised Latin translations based on the demotic and hieroglyphic texts. The first English translation followed in 1858, the work of three members of the Philomathean Society at the University of Pennsylvania. Whether one of the three texts was the standard version, from which the other two were originally translated, is a question that has remained controversial. Letronne attempted to show in 1841 that the Greek version, the product of the Egyptian government under the Macedonian Ptolemies, was the original. Among recent authors, John Ray has stated that "the hieroglyphs were the most important of the scripts on the stone: they were there for the gods to read, and the more learned of their priesthood".
