When the famous English archaeologist Flinders Petrie was excavating the royal cemetery in Abydos in the year 1900, the oldest royal "serek" came to light indicating a king. It's a standing rectangle imitating the royal residence and its facade with the king's name written in it, like in the picture left. The sign with two arms reaching for the sky has always been the word "ka" in the Egyptian language, meaning - soul. Based on the fact that his name was painted and carved on lots of potsherds, his tomb was identified placed between those of Narmer and Iry-Hor. He is believed to have reigned in the late dynasty "0", one generation prior to the final unification.
