Ancient Egypt was an ancientcivilization of eastern North Africa, concentrated along the lower reaches of the Nile River in what is now the modern country of Egypt. The civilization coalesced around 3150 BC with the political unification of Upper and Lower Egypt under the first pharaoh, and it developed over the next two millennia. Ancient Egypt reached its pinnacle during the New Kingdom, after which it entered a period of slow decline. Egypt was conquered by a succession of foreign powers in this late period, and the rule of the pharaohs officially ended in 31 BC when the early Roman Empire conquered Egypt and made it a province.
Egypt has left a lasting legacy for all to see. Its art and architecture has been widely copied, and its antiquities have been carried off to the far corners of the world. Egypt's monumental ruins have inspired the imaginations of travelers and writers for centuries. A newfound respect for antiquities and excavations in the early modern period led to the scientific investigation of Egyptian civilization and a greater appreciation of its cultural legacy for the earth.
The hieroglyph for Sothis features a star and a triangle. Sothis was identified with the great goddess Isis, who formed a part of a trinity with her husband Osiris and their son Horus, while the 70-day period symbolised the passing of Isis and Osiris through the duat (Egyptian underworld). Ptolemy of Alexandria mapped the stars in Book VII and VIII of his Almagest, in which he used Sirius as the location for the globe's central meridian. He curiously depicted it as one of six red-coloured stars
Ahmose I (sometimes written Amosis I, "Amenes" and "Aahmes" and meaning Born of the Moon or Born of Yah) was a pharaoh of ancient Egypt and the founder of the Eighteenth dynasty. He was a member of the Theban royal house, the son of pharaoh Tao II Seqenenre and brother of the last pharaoh of the Seventeenth dynasty, King Kamose. During the reign of his father or grandfather, Thebes rebelled against the Hyksos, the rulers of Lower Egypt. When he was seven his father was killed, and he was about ten when his brother died of unknown causes, after reigning only three years. Ahmose I assumed the throne after the death of his brother, and upon coronation became known as Neb-Pehty-Re (The Lord of Strength is Re).
