Heti (or more briefly, Het) is attested through seal impressions found in Abydos, Naqada and Saqqara, three major cities at the start of the 1st Dynasty. His name is found in combination with that of Horus Aha, indicating that he was a high official during Aha’s reign.
Although the type of seal that combines the name of a king with that of a private person is sometimes seen as a Prince’s seal, this is based purely on the assumption that only members of the royal family would, at this time, hold high offices. But even if this were the case, the seals would still not prove an affiliation and this type of seal can thus not be seen as evidence that the holder was the son of the king.
Heti’s name sometimes also appears next to that of two of his contemporaries: Rekhit in Naqada and Saiset in Saqqara, where he appears to only have a secondary position. This would indicate that the three high officials of Aha’s reign, each may have held their office in one of Egypt’s three major cities.
Rejecting the hypothesis of the Prince’s seals, the relationship between these three officials is not known.
