The sources of the Nile from an old latin book (different from the one mentioned)
Apospasmatia Geographica (ab.700)
Taken from: The Michigan Teacher, Volumes 2-3
With regard to the sources of the Nile the following is the state of the case. From the great Mountains of the Moon flow eight streams, four from its western, four from its eastern part. Their order, reckoned from west to east, is first the western stream, the Cherbalas (5), second the Chamset (6). They unite near the city of Metis (7), and flow farther after this union. The third river is the Chiagonas (8), the fourth the Ganbalas (9). These four discharge into a lake called the Lake of Waterfalls (3). The other four eastern rivers lie in the following order: the first, which flows through the land of the Pigmies (10), has no name, neither the second. They unite and form one stream. The third is also nameless; but the fourth, the farthest to the east, is called Charalas (11). The four discharge into a basin, named the lake of Crocodiles. From the lake of Waterfalls (3) flow two streams which later unite by the cities of Chiera and Chaza (12). From the lake of Crocodiles (3) in like manner flow two streams uniting near the cities of Singos (13) and Aba (14). These two and those which unite by Chaza (12), form by their combination the great stream in the land of the Elephantophagi (14). Between both extends the Cinnamon Land (15) and the region of the Pigmies (10). Farther down, the great river flows through the land of the Champesides (4), where it receives the Astapus (1) from lake Chole (2).
(1) The Blue Nile (from Ethiopia). Astapus is used in the works of: Diodorus-Siculus, Strabo, Pliny the Elder, Solinus, Ptolemaeus.
(2) this is the lake from which the Bleu Nile starts; now called lake Tana. Named lake Koloe with Ptolemaeus.
(3) both should be the western or eastern lake of the Nile; both with many crocodiles.
(4) Champesides, tribe in Upper Egypt on the Nile, whose seats seem to have been south of the confluence of the Astapus (Bahr el Azrek). Only found in this text. But Müller refers it to Therai in Ptol. IV 7, 7.
