Behistun Inscription
Work on the ancient languages of the Near East progressed rapidly. In the mid-19th century, Henry Rawlinson and others deciphered the Behistun Inscription, which records the same text in Old Persian, Elamite, and Akkadian, using a variation of cuneiform for each language. The elucidation of cuneiform led to the decipherment of Sumerian. Hittite was deciphered in 1915 by Bedřich Hrozný.
