 These expeditions departed Egypt from the port of Ain <unk> , on the western shore of the Gulf of Suez , as revealed by papyri and seals bearing Djedkare Isesi 's name found on the site . The port comprised large galleries carved into the sandstone serving as living quarters and storage places . The wall of one such gallery was inscribed with a text mentioning yet another expedition to the hills of turquoise in the year of the seventh cattle count – possibly Djedkare 's 14th year on the throne .
