Aware that his reputation was then more as a linguist than an archaeologist, Maspero's first work in the post was to build on Mariette's achievements at Saqqara. He expanded their scope from the early Old Kingdom to the later, with particular interest in tombs with long and complete hieroglyphic inscriptions that could help illustrate the development of the Egyptian language. Selecting five later Old Kingdom tombs, he was successful in that aim, finding over 4,000 lines of hieroglyphics which were then sketched and photographed.
