From The Story Of Writing

The decipherment of cuneiform script owes much to Rawlinson’s athleticism, as can be seen by the sheer rock face he repeatedly scaled to copy the Old Persian, Elamite and Babylonian inscriptions carved more than 300 feet above the roadbed in Behistun. In this lithograph published in 1846, the tiny figure standing on a ledge, pointing to the inscription, is Rawlinson himself.
