In the great ceremonies connected with this god, and especially on the day of his festival, a boat called the Seker-boat was placed upon a sledge at sunrise, at the time when the rays of the sun were slowly beginning to diffuse themselves over the earth. It was then drawn round the sanctuary, which act typified the revolution of the sun. This boat was known as Henu, and is mentioned several times in the _Book of the Dead_. It did not resemble an ordinary boat, but one end of it was much higher than the other, and was fashioned in the shape of the head of an animal resembling a gazelle. In the centre of the vessel was a coffer surmounted by a hawk with outspread wings, which was supposed to contain the body of Osiris, or of the dead Sun-god. The Seker- or Henu-boat was probably a form of the Mesektet-boat, in which the sun sailed over the sky during the second half of his daily journey, and in which he entered the underworld in the evening. Although Seker was fairly popular as a deity in ancient Egypt, his attributes seem to have been entirely usurped by Ptah. We also find the triple-named deity Ptah-Seker-Asar or Ptah-Seker-Osiris, who is often represented as a hawk on coffers and sarcophagi. About the Twenty-second Dynasty this triad had practically become one with Osiris, and he had even variants which took the attributes of Min, Amsu, and Khepera. He has been described as the 'triune god of the resurrection.' There is very little doubt that the amalgamation of these gods was brought about by priestly influence. Ptah was also connected with the god known as Tenen, who is usually represented in human form and wearing on his head the crown with ostrich feathers. He is also drawn working at a potter's wheel, upon which he shapes the egg of the world. In other drawings he is depicted as holding a scimitar. Dr. Budge suggests that this weapon shows that he is the destructive power of nature or the warrior-god, but this is most unlikely. The scimitar of Ptah in his guise as Tenen is precisely the same as those axes which are the attributes of creative deities all over the world. With this scimitar he carves out the earth, as the god of the Ainu of Japan shapes it with his hatchet, or as other deities which have already been mentioned use their axes or hammers. Tenen was probably a primeval creative god, but for that reason was co-ordinated with Ptah. Sekhmet The principal centre of the worship of Ptah was Memphis, in which were also situated the temples of Sekhmet,[5] Bast, Osiris, Seker, Hathor, and I-em-hetep, as well as that of Ra. The female counterpart of Ptah was Sekhmet, and they were the parents of Nefer-tem. Sekhmet was later identified with forms of Hathor. She had the head of a lioness, and may be looked upon as bearing the same relation to Bast as Nephthys bears to Isis. She was the personification of the fierce destroying heat of the sun's rays. One of her names is Nesert, flame, in which she personifies the destroying element.
