Betrest is said to have been the mother of
Semerkhet. Her name appears in Line III on the Cairo stone fragment
C1, where she bears the title
Mut (meaning "mother"). The name of the person on the stela included a ram-hieroglyph (which commonly reads "Ba") and the signs "s" and "t" are visible. If this monument belongs to Queen Betrest, then it also preserves part of a title with a
Horus-falcon sign, which may be part of the
She Who Sees Horus title, which is a common title for royal queens in the
Old Kingdom of ancient Egypt. Silke Roth and Toby Wilkinson point out, however, that the ram-hieroglyph was read differently in early times. The reading as "Ba" (meaning "soul"), does not appear before the Old Kingdom period and during the two first dynasties the ram-sign was read as,
Khnemu (for the deity
Khnum) or
Ser (meaning "sheep", "ram", or "begetter"). This reading is promoted by the hieroglyph for "s" on the stela. In sum the reading on the stela had to be
Seret, which means "mother sheep" or "she of the ram". It seems that the later ramesside scribes, who compiled the Annal stone (and therefore the Cairo stone inscription), had no knowledge of the older readings for the ram sign and simply read "Ba", changing
Seret into
Batyires. == Tomb ==
