The place is now known by the Arabic name of Umm al-Ka’âb or “Mother of Pots” on account of the large quantity of pottery that has been found there. 39 Ed. Meyer, _Geschichte des Altertums_,2 i. 2. pp. 119, 125, 127, 128, 129, 209. The king’s Horus name has sometimes been read Zer, but according to Professor Meyer (_op. cit._ p. 128) and Dr. Budge (_Osiris and the Egyptian Resurrection_, ii. 83) the true reading is Khent (Chent). The king’s personal name was perhaps Ka (Ed. Meyer, _op. cit._ p. 128). 40 E. Amélineau, _Le Tombeau d’Osiris_ (Paris, 1899), pp. 107-115; W. M.

The masses, almost the mountains, of broken pottery, under which the tomb was found to be buried, are probably remains of the vessels in which pious pilgrims presented their offerings at the shrine. See E. Amélineau, _op. cit._ pp. 85 _sq._; J. H. Breasted, _op. cit._ pp. 51, 148. The high White Crown, worn by Osiris, was the symbol of the king’s dominion over Upper Egypt; the flat Red Crown, with a high backpiece and a projecting spiral, was the symbol of his dominion over Lower Egypt. On the monuments the king is sometimes represented wearing a combination of the White and the Red Crown to symbolize his sovereignty over both the South and the North. White was the distinctive colour of Upper, as red was of Lower, Egypt. The treasury of Upper Egypt was called “the White House”; the treasury of Lower Egypt was called “the Red House.” See Ed. Meyer, _Geschichte des Altertums_,2 i. 2. pp. 103 _sq._; J. H. Breasted, _History of the Ancient Egyptians_ (London, 1908), pp. 34 _sq._, 36, 41.
