Horus Sa
Horus Sa (also Horus Za, Sa and Za) was a possible early Egyptian pharaoh who may have reigned during the Second or Third Dynasty of Egypt. His existence is disputed, as is the meaning of the artifacts that have been interpreted as confirming his existence. Attestations. Horus Sa is known from vessel fragments with black ink inscriptions showing his name. These vessels were found in the east galleries beneath Djoser's pyramid at Saqqara. The inscriptions are short and written in cursive handwritings. In all cases the name "Horus Sa" does not appear within a "serekh" and its  identification as the Horus-name of a king is disputed. The name "Horus Sa" always appears within the inscription "Ḥwt-k3 Ḥrw-z3" ("House of the Ka of Horus Sa"), regularly found together with the names of "Inykhnum" and "Ma'a-aper-Min", two high-ranking officials who served in the "Ka"-house. During the Early Dynastic Period of Egypt, the House of the Ka was a forerunner of the mortuary temple, a place where a cult to the Ka of a deceased ruler was performed. A further inscription, "Ḥwt-k3 Ḥrw-z3", was found in the 1980s at Saqqara in the  area of the tomb of Maya and very close to that of Meryra-Meryneith. Maya and Meryra-Meryneith were both late 18th dynasty court officials who reused 2nd dynasty tombs for themselves, some 1,500 years after the death of their original owners. Identity. Jürgen von Beckerath, Dietrich Wildung and Peter Kaplony proposed that "Sa" is a short form of the Horus-name Sanakht. Wolfgang Helck rejects this argument on the grounds that the ink inscriptions from the east-galleries of Djoser's pyramid complex date predominantly from the reign of Nynetjer or shortly thereafter, while Sanakht reigned during the mid-3rd  dynasty. Furthermore, inscriptions mentioning the "House of the Ka of Hotepsekhemwy" are stylistically similar to that of Horus Sa which would place Sa in the 2nd dynasty since Hotepsekhemwy was the first ruler of that dynasty. Thus, Helck proposed that Horus Sa is the Horus-name of another shadowy ruler of the 2nd dynasty, Weneg, whose Horus-name is otherwise unknown. The Egyptologist Jochem Kahl recently challenged this hypothesis, identifying Weneg with Raneb. Alternatively, Kaplony reconstructed the Horus-name of Weneg from the Cairo fragment of the Palermo stone as Wenegsekhemwy. In both cases, Horus Sa cannot be the  Horus-name of Weneg and the two would not designate the same king. Consequently, Kaplony equated Horus Sa with "njswt-bity Wr-Za-Khnwm", "The king of Upper and Lower Egypt, Wersakhnum" and credited him a reign of 2 months and 23 days during the interregnum between Khasekhemwy and Djoser. However, Kaplony's hypothesis has been undermined by the discovery of clay seals of Djoser in Khasekhemwy's tomb, indicating that the former immediately succeeded and buried the latter. Horus Sa could instead be the Horus-name of Senedj or another 2nd dynasty king, ruling in Memphis during the troubled  period following the reign of Nynetjer. However, Egyptologists such as Jean-Philippe Lauer, Pierre Lacau and Ilona Regulski call for caution of the correct reading of the inscriptions. Especially the bird-sign at the top of the "Ka"-house might also depict a swallow, which would make the inscription to be read as "Wer-sa-hut-Ka" ("great protection of the Ka-house"). Regulski prefers the reading as a Horus-bird, though she doesn't explicitly see it as the name of a king. She dates the inscriptions to the end of Khasekhemwy's reign. Tomb. The burial place of Horus  Sa is unknown. Nabil Swelim associated Horus Sa with the unfinished enclosure of Gisr el-Mudir in west Saqqara. This hypothesis has not gained wide acceptance and the Gisr el-Mudir has been attributed to various second dynasty kings, in particular Khasekhemwy. Alternatively, the Egyptologist Joris van Wetering proposed that the gallery tomb used by the high priest of Aten, Meryra-Meryneith, in north Saqqara was originally that of Horus Sa, since an inscription "Ḥwt-k3 Ḥrw-z3" was found in the close vicinity of the tomb.
