Although Strabo cited the classical Greek astronomers Eratosthenes and Hipparchus , acknowledging their astronomical and mathematical efforts covering geography, he claimed that a descriptive approach was more practical, such that his works were designed for statesmen who were more anthropologically than numerically concerned with the character of countries and regions. As such, Geographica provides

6882-552: The only surviving document is a fragment of papyrus now in the possession of the University of Milan (renumbered [Papyrus] 46). Strabo studied under several prominent teachers of various specialities throughout his early life at different stops during his Mediterranean travels. The first chapter of his education took place in Nysa (modern Sultanhisar , Turkey) under the master of rhetoric Aristodemus , who had formerly taught
6975-513: The original sources of indigo dye . Another may be Nymphaea caerulea , known as "The Sacred Blue Lily of the Nile", which was found scattered over Tutankhamun 's corpse when it was excavated in 1922. Another possible etymology derives from the Semitic term Nahal , meaning "river". Old Libyan has the term lilu , meaning water (in modern Berber ilel ⵉⵍⴻⵍ means sea ). With a total length of about 6,650 km (4,130 mi) between
7068-401: The phenomena, and he proposes one of his own, the profoundness of which modern geologists are only beginning to appreciate. 'It is not,' he says, 'because the lands covered by seas were originally at different altitudes, that the waters have risen, or subsided, or receded from some parts and inundated others. But the reason is, that the same land is sometimes raised up and sometimes depressed, and
7161-575: The present course of the Nile in Egypt and Sudan. Rushdi Said postulates that Egypt supplied most of the waters of the Nile during the early part of its history. The other theory is that the drainage from Ethiopia via rivers equivalent to the Blue Nile, the Atbara and the Takazze flowed to the Mediterranean via the Egyptian Nile since well back into Tertiary times. Salama suggests that during
7254-417: The quarries lie in front of the pyramids. Among these are found pieces which in shape and size resemble lentils. Some contain substances like grains half peeled. These, it is said, are the remnants of the workmen's food converted into stone; which is not probable. For at home in our country (Amaseia), there is a long hill in a plain, which abounds with pebbles of a porous stone, resembling lentils. The pebbles of
7347-462: The region of Lake Victoria and the Mediterranean Sea , the Nile is among the longest rivers on Earth. The drainage basin of the Nile covers 3,254,555 square kilometers (1,256,591 sq mi), about 10% of the area of Africa. Compared to other major rivers, though, the Nile carries little water (5% of that of the Congo River , for example). The Nile basin is complex, and because of this,
7440-655: The reign of Mithridates V . Strabo was related to Dorylaeus on his mother's side. Several other family members, including his paternal grandfather, had served Mithridates VI during the Mithridatic Wars . As the war drew to a close, Strabo's grandfather had turned several Pontic fortresses over to the Romans. Strabo wrote that "great promises were made in exchange for these services", and as Persian culture endured in Amaseia even after Mithridates and Tigranes were defeated, scholars have speculated about how
7533-685: The river is called Kiira or Kiyira . In Runyoro , it is called Kihiira . In Egyptian Arabic , the Nile is called en-Nīl , while in Standard Arabic it is called an-Nīl . In Biblical Hebrew , it is הַיְאוֹר , Ha-Ye'or or הַשִׁיחוֹר , Ha-Shiḥor . The English name Nile and the Arabic names en-Nîl and an-Nîl both derive from the Latin Nilus and the Ancient Greek Νεῖλος . Beyond that, however,
7626-670: The river south-west for over 300 km, following the structure of the Central African Shear Zone embracing the Bayuda Desert . At Al Dabbah it resumes its northward course towards the first cataract at Aswan forming the S-shaped Great Bend of the Nile mentioned by Eratosthenes . In the north of Sudan, the river enters Lake Nasser (known in Sudan as Lake Nubia), the larger part of which
7719-532: The riverbed sufficiently for the river to overflow westward into a depression to create Lake Moeris . Lake Tanganyika drained northwards into the Nile until the Virunga Volcanoes blocked its course in Rwanda. The Nile was much longer at that time, with its furthest headwaters in northern Zambia. The currently existing Nile first flowed during the former parts of the Würm glaciation period. Affad 23
7812-407: The scientific community and interest by other explorers keen to either confirm or refute Speke's discovery. British explorer and missionary David Livingstone pushed too far west and entered the Congo River system instead. It was ultimately Welsh-American explorer Henry Morton Stanley who confirmed Speke's discovery, circumnavigating Lake Victoria and reporting the great outflow at Ripon Falls on
7905-401: The sea also is simultaneously raised and depressed so that it either overflows or returns into its own place again. We must, therefore, ascribe the cause to the ground, either to that ground which is under the sea, or to that which becomes flooded by it, but rather to that which lies beneath the sea, for this is more moveable, and, on account of its humidity, can be altered with great celerity. It
7998-588: The sea level rose at the end of the most recent ice age , the stream which is now the northern Nile captured the ancestral Nile near Asyut . This change in climate also led to the current extents of the Sahara desert, around 3400 BCE. The Giza pyramid complex originally overlooked a branch of the Nile that no longer exists. This branch was highest during the African Humid Period . The existing Nile has five earlier phases: Flowing north from
8091-453: The sea-shore and of rivers suggest somewhat of the same difficulty [respecting their origin]; some explanation may indeed be found in the motion [to which these are subject] in flowing waters, but the investigation of the above fact presents more difficulty. I have said elsewhere, that in sight of the pyramids, on the other side in Arabia, and near the stone quarries from which they are built, is
8184-627: The sons of the Roman general who had taken over Pontus. Aristodemus was the head of two schools of rhetoric and grammar, one in Nysa and one in Rhodes . The school in Nysa possessed a distinct intellectual curiosity in Homeric literature and the interpretation of the ancient Greek epics. Strabo was an admirer of Homer 's poetry, perhaps as a consequence of his time spent in Nysa with Aristodemus. At around
8277-473: The time of Nero (54–58 AD). It was conquered by Constantinus in 312 AD. They are attested on the Arch of Susa , erected by Cottius in 9–8 BC. Strabo Strabo ( / ˈ s t r eɪ b oʊ / ; Greek : Στράβων Strábōn ; 64 or 63 BC – c. 24 AD ) was a Greek geographer , philosopher , and historian who lived in Asia Minor during the transitional period of
8370-560: The western shores of the lake and flows at first to the west until just south of Masindi Port , where the river turns north, then makes a great half circle to the east and north to Karuma Falls . For the remaining part, it flows westerly through the Murchison Falls until it reaches the northern shores of Lake Albert where it forms a significant river delta. Lake Albert is on the border of the Democratic Republic of
8463-574: Was enough to fill and connect them. The Egyptian Nile connected to the Sudanese Nile, which captures the Ethiopian and Equatorial headwaters during the current stages of tectonic activity in the Eastern, Central and Sudanese Rift systems. The connection of the different Niles occurred during cyclic wet periods. The Atbarah overflowed its closed basin during the wet periods that occurred about 100,000 to 120,000 years ago. The Blue Nile connected to
8556-597: Was even less understood. The ancients mistakenly believed that the Niger River represented the upper reaches of the White Nile. For example, Pliny the Elder writes that the Nile had its origins "in a mountain of lower Mauretania ", flowed above ground for "many days" distance, then went underground, reappeared as a large lake in the territories of the Masaesyli , then sank again below the desert to flow underground "for
8649-400: Was more relevantly a respected authority on geography, a fact of some significance considering Strabo's future contributions to the field. The final noteworthy mentor to Strabo was Athenodorus Cananites , a philosopher who had spent his life since 44 BC in Rome forging relationships with the Roman elite. Athenodorus passed onto Strabo his philosophy, his knowledge and his contacts. Unlike
