With the Persian text, and with about a third of the syllabary made available to him by the work of Georg Friedrich Grotefend, Rawlinson set to work on deciphering the text. The first section of this text contained a list of the same Persian kings found in Herodotus but in their original Persian forms as opposed to Herodotus's Greek transliterations; for example Darius is given as the original "Dâryavuš" instead of the Hellenized "Δαρειος". By matching the names and the characters, Rawlinson deciphered the type of cuneiform used for Old Persian by 1838 and presented his results to the Royal Asiatic Society in London and the Société Asiatique in Paris.
