Neferirkara Kakai. His throne name was Nefer-ir-ka-re (Beautiful is the Soul of Re) while his birth name was Kakai. He was the third king of the Old Kingdom 5th dynasty, ruling from about 2477 until 2467 BC. He was the first king to have employed both a prenomen and nomen (he had two names and two cartouches), a custom that later kings would follow. Also, papyrus found in his pyramid complex were written in ink and are the earliest known documents in hieratic script, a cursive form of hieroglyphics.
