It is debatable whether or not Imhotep, the son of ptah and Sekhmet whose name meant "he who comes in peace," is the third member of the triad of Memphis. He is depicted as a bald-headed man in a scribe-like posture with papyrus on his knees.
Among his names are the "Great One, Son of Ptah, the Creative God, made by Thenen, Begotten by Him and Beloved by Him, the God of Divine Forms in the Temples, who Gives Life to All Men, the Mighty One of Wonders, the Maker of Times and many other names deifying his great power and blessings.
Recognized as a god of medicine who sent sleep to those in severe pain and suffering, Imhotep was famous for his healing abilities and curative powers, the reason why he was often associated with Thuth, the god of wisdom. The worshipers of Imhotep were usually sacrificing Ibisis in his tomd and sick people pled for being healed by Imhotep's miraculous cures.
One of the most interesting myths of Imhotep highlights his role as the god who helps women to give birth in boys. The tale relates that a miserable married couple had no male heirs went to a temple of Imhotep and pled for giving birth to a boy. Falling asleep in the temple, she had a dream that instructed her to make a medicine for her husband from the root of a certain plant, the colocasia. As she did, she became pregnant with a baby boy.
Besides being Zoser's chief advisor early in the Third Dynasty (2686 B.C), Imhotep was the architect of both the funerary complex and the King's Step Pyramid at Saqqara. In a famous myth, his duty as an advisor is highly manifested. That myth relates that Zoser went to Aswan to plead the god for stopping a famine that struck Egypt. After consulting his books, Imhotep said that the reason of god Khnum's rage was Zoser's negligence of the Temple of the god. Thus, he prescribed that a journey should be made to the angered god to whom the king should pay the due tribute.
Though not a king and merely a man of a lower position, Imhotep was largely defied, especially after nearly two thousand years after his death. In Imhotep's honor, temples were erected at Memphis, Philae, and Thebes and a school of medicine and magic was built for him at a hospital at Memphis. Probably, his tomb (not yet discovered) lies somewhere in the funeral complex at Saqqara.
