The Alexandria library was more permanent. Included in the tremendous collection of some 700,000 volumes

Equal to 50,000 modern books. (Ref. 15 )
was the "corpus Hippocratum" made up of some genuine Hippocratic writings but also treatises and notes of his pupils and even some material from a rival medical school at Cnidus. Eratosthenes became librarian in 235 B.C. and became the founder of the science of geography by making maps and conceiving the idea of projections. In 239 B.C. he calculated the circumference of the earth at 28,000 miles, an error of only 13%. This means that a degree of latitude was thought to be 60 miles, rather than the true 69 miles, an error not great enough to forestall ocean crossings with a fair degree of certain landing. He based his calculations on the proposition that the earth was a sphere and that the sun's rays for practical purposes may be considered to be parallel. Longitude was calculated by dead reckoning. Eratosthenes also reported that papyrus ships, with sails and rigging as on the Nile, sailed as far as the mouth of the Ganges and Ceylon, taking perhaps twenty days to go from the former to the latter, thus averaging about 75 miles per day, a speed of more than three knots an hour. (Ref. 15 , 65 , 66 , 95 )

Toward the end of the century radical decay set in, with bureaucratic corruption and slackness. As the century ended the aggressive Syrian king, Antiochus III, defeated the child Ptolemy V and took the Mediterranean coastal possessions of Palestine, Phoenicia and Asia Minor away from the Egyptian Dynasty. There is some indication that bubonic plague, or something very similar, made its first appearance in Egypt and adjacent Libya in this century and then disappeared again for another 800 years. (Ref. 140 )

Carthage was now the richest of the Mediterranean cities, trading in slaves, Egyptian linen, ivory, animal skins, Greek pottery and wine, iron from Elba, copper from Cyprus, silver from Spain, tin from Britain and incense from Arabia. Some Carthaginian planters occupying fertile land in Libya may have had as many as 20,000 slaves. (Ref. 222 ) In 261 B.C. Carthage supposedly had 1,500 ships with approximately 150,000 crewmen. This is to be compared with the famous Spanish Armada of A.D. 1588 when Spain had 120 ships and 27,000 crew-men, Carthage soon reduced Numidia to a series of vassal states and became the capital of a Semitic empire which spread all along north Africa as well as in the islands of the Mediterranean and in Spain. Although the level of civilization was high in most respects, some of their customs were barbaric, such as sacrificing living children to certain male and female gods. The details of Carthage's great struggles with Rome will be given in later sections under ITALY and SPAIN. It will suffice to say at this time that at the end of the First Punic War a local revolution broke out in Carthage which raged for forty months. And still Carthage bounced back to fight the greater Second Punic War with Rome. At the end of this second conflict, when Hannibal was defeated by Scipio at the gates of the city, it was the beginning of the end of this great city-state, although it struggled on until the middle of the next century. (Ref. 48 , 66 )

It is somewhat difficult for us today to grasp the magnitude of the Punic Wars. The First was marked by some of the greatest sea battles in history. Consider the following, as collected from ancient historians by Fell (Ref. 66 ):

Date Name Roman Ships Carthage Ships Carthage Losses
260 B.C. Battle of Mylae 150 ships 150 ships 50 ships
256 B.C. Battle of Economus 230 ships 230 ships 84 ships
255 B.C. Battle pf Hermaean Cape 200 ships 200 ships 100 ships
242 B.C. Battle of Aegates Island 200 ships 100 ships 100 ships
Total ships lost 334 ships

Each Carthaginian ship had a crew of at least 250 rowers, with 120 more officers and marines. The losses of men in these great sea battles must have been staggering.

Another interesting fact about Carthage at this period is that their coins changed from silver to gold, but with just a small amount of gold - the amalgam called "electrum" - at about 300 B.C. The design also changed to depict the native Carthaginian goddess, Tanith, spouse of Bel. Based on findings since 1976 of alleged Carthaginian coins of this period found in various north American sites, Fell (Ref. 66 ) believes that the source of the Carthaginian gold was America, obtained from Amerindians in bartering with bronze manufactures of the Cypriot Phoenicians. Such bronze works are now held in storage rooms in Cuenca, Brazil, collected by Professor Paul Cheeseman. This region was a former Inca northern capital, noted for burial hoards and underground valuables. Fell also believes that these same North African mariners traded with North American Algonquin tribes for timber which they used for ships. After the terrible naval defeats by Rome and the absence of a navy, trade with America was no longer profitable or even possible.

In northern Nigeria the so-called Nok Culture has been identified with terra-cotta figurines, and evidence of iron slag and tin-mining, dated by radio-carbon technique to about 300 B.C. Along the high cliffs of Bandiagara on the edge of the Hombori Mountains near the bend of the Niger River in Mali, the Toloy people built granaries of mud coils and stored them in giant caves in the cliffs, while their villages were probably on the plains below. (Ref. 251 ) Along the Congo River there were Stone Age gathers and fishermen about 270 B.C. In the east and south there was a continued take-over by the Sudanese Negroes who were now called Bantu, after their language. (Ref. 45 , 8 )

Forward to Africa: 200 to 101 B.C.
