The Prussian expedition assembled in Alexandria in 1842 and quickly departed for Giza, which was reached in November that same year. Proceeding north to south, Lepsius's men then explored the pyramids field of Abusir, Saqqara, Dahshur and, in 1843, Hawara. Lepsius and team stayed for 6 months in total at these locations, as the Prussian expedition was the first study and record Old Kingdom material in depth.[1]
