The Egyptian Book of the dead by P. Le Page Renouf and Edouard Naville

10. _Ponds._ The right reading is ⁂⁂⁂, as Birch already noted

in his _Dictionary_, from the excellent papyrus _Ao_ of the XVIIIth dynasty. Hieratic papyri also give the determinative ⁂. The determinative ⁂ which some of the papyri give to the word, and which is a self-evident blunder, is probably copied either from ⁂, or from ⁂. The sign ⁂, and a man striking with an instrument, which also occur, are mere symbols of the operation by which either _quarries_, or _ponds_, are _cut_.
