Djet, also known as Wadj, Zet, and Uadji (in Greek possibly the pharaoh known as Uenephes or possibly Atothis), was the fourth Egyptian pharaoh of the first dynasty. Djet's Horus name means “Horus Cobra” or “Serpent of Horus”.
Djet's queen was his sister Merneith, who may have ruled as a Pharaoh in her own right after his death. There is a possibility that a lady called Ahaneith was also one of his wives. Djet and Merneith's son was Den, and their grandson was Anedjib.
How long Djet ruled is unknown. Only one Sekar festival is attested by ivory labels dating to his reign, whose duration is estimated to be anywhere between six to ten years. According to Wolfgang Helck he reigned 10 years. From a calendar entry, Djer is known to have died on a 7 Peret III while Djet began his reign on 22 Peret IV. The reason for the 45 days of interregnum is unknown.
Details of Djet's reign are lost in the lacunas of the Palermo Stone. However, finds of vessel fragments and seal impressions prove that there were intense trading activities with Syria and Palestine at the time. Graves at Tarkhan and Saqqara dating to his reign yielded pottery from Palestine. Other activities can be inferred from the only two known years tablets of the ruler, one of which is preserved in two copies. The reading of the events described on the tablets is highly problematic. Helck translated: "Year of the planning of the underground/basement (?) of the dual plant, birth of lotus buds, standing in the crown shrine of the two Ladies." The other year tablet mentions a victory, the production (birth) of a statue and perhaps the creation of a fortress. Finally, in Masra Alam in Nubia, the short inscription "Hemka" below "Djet" was discovered.
