Some fragmentary reliefs found at Heliopolis and Gebelein mention Djoser's name, and suggest he commissioned construction projects in those cities. Also, he may have fixed the southern boundary of his kingdom at the First Cataract. An inscription known as the Famine Stela and claiming to date to the reign of Djoser, but probably created during the Ptolemaic Dynasty, relates how Djoser rebuilt the temple of Khnum on the island of Elephantine at the First Cataract, thus ending a seven-year famine in Egypt. Some consider this ancient inscription as a legend at the time it was inscribed. Nonetheless, it does show that more than two millennia after his reign, Egyptians still remembered Djoser.
