[1][2][3] The incomplete stela was made during the reign of Ramesses II of the 19th Dynasty; this pharaoh appears in the lunette while offering wine jars to Seth, whose name was erased when this deity was demonised in later times.

[1][4] The inscription on the lower register says that Seti, son of Paramessu and Tia, came to worship Seth and commemorate this event by issuing the granite stela; curiously, and with the approval of Ramesses II, Seti dated the stela to the “Year 400, fourth day of the fourth month of the Season of the Inundation” of a pharaoh named Aapehtiseth Nubti[1][4] (“Great is the strength of Seth, he of Ombos”): Since the discovery it was obvious that the Year 400 of Nubti was not a regnal year, but rather a sort of anniversary.

Giving the 400-years interval and the explicit references to the god Seth, Nubti was initially considered an othervise unattested Hyksos ruler.

[1][4][5] Thus, it was suggested that the 400th anniversary could refer to an important event such as the construction of a temple of Seth,[6] or, more generally, to the beginning of a new era.

Going 400 years back before the period suggested by the stela (most likely when Seti was an official under king Horemheb), gives a datation of the celebrated event of around 1730–1720 BCE.
