Merer
The first and second diaries reveal that Merer and his crew work for several months transporting limestone from Tura to Giza in the 26th or 27th year of the reign of Egyptian pharaoh Khufu. About every ten days, two or three round trips were done, shipping approximately 30 blocks of 2—3 tonnes each, amounting to approximately 200 blocks per month. In the diaries, Merer mentions that he and his crew opened giant dykes to divert water from the Nile, channeling it into canals leading it into the Great Pyramid of Giza. Around forty boatmen worked under Merer. The period covered in the diaries spans a few months.
