Trade

The ancient Egyptians engaged in trade with their foreign neighbors to obtain rare, exotic goods not found in Egypt. In the predynastic, they established trade with Nubia to obtain gold and incense. They also established trade with Palestine, as evidenced by Palestinian type oil jugs found in burials of the First Dynasty pharaohs.[2]

By the Second Dynasty the ancient Egyptians had established trade with Byblos, a critical source of quality timber not found in Egypt. In the Fifth Dynasty, trade was established with the Land of Punt, which provided gold, aromatic resins, ebony, ivory, and wild animals such as monkeys and baboons.

Egypt relied on trade with Anatolia for supplies of tin, a component of bronze which was not mined by the ancient Egyptians, and supplementary supplies of copper. The ancient Egyptians prized the blue stone lapis lazuli, which had to be imported from far-away Afghanistan. Egypt's Mediterranean trade partners also included ancient Greece and Crete, which provided, among other goods, supplies of olive oil.[1] Hatshepsut is known to have imported live trees for transplantation into her gardens.

In exchange for its luxury imports and raw materials, Egypt mainly exported gold and papyrus, in addition to some finished goods including glass objects. The first glass beads are thought to have been manufactured in Egypt.

The ancient Egyptian military was responsible for maintaining Egypt's domination in the ancient near-east. The military protected mining expeditions to the Sinai in the Old Kingdom and fought civil wars during the First and Second Intermediate Periods. The military was responsible for maintaining forts along important trade routes, for example at the city of Buhen on the way to Nubia. Forts also were constructed to serve as military bases, such as the fortress at Sile, which was a base of operations for expeditions to the Levant. In the New Kingdom, a series of pharaohs used the standing Egyptian army to attack and conquer Kush and territory in the levant.[2]

Typical military equipment included round-topped shields made of animal skin stretched over a wooden frame, bows and arrows, and spears. In the New Kingdom, the military began using chariots which were introduced by Hyksos invaders in the Second Intermediate Period. Weapons and armor continued to improve after the adoption of bronze. Shields were now made from solid wood with a bronze buckle, spears were tipped with a bronze point, and a type of scimitar made of bronze, the Khopesh, was adopted from Asian soldiers.[4]

The Egyptian pharaoh usually is depicted in art and literature leading at the head of the Army, and there is certain evidence that at least a few pharaohs are known to have, such as Seqenenre Tao II and his sons.[2] Soldiers were recruited from the general population, but during and especially after the New Kingdom, mercenaries from Nubia, Kush, and Libya were hired to fight for Egypt under the command of their own officers.[4]

Achievements and unsolved problems

The achievements of ancient Egypt are well known, and the civilization achieved a very high standard of productivity and sophistication. Hydraulic cement was first invented by the Egyptians.

The earliest evidence (circa 1600 BC) of traditional empiricism is credited to Egypt, as evidenced by the Edwin Smith and Ebers papyri. The roots of the scientific method may be traced back to the ancient Egyptians. The Egyptians created their own alphabet (however, it is debated as to whether they were the first to do this because of the margin of error on carbon dated tests), the decimal system.[44]

Glass making was highly developed in ancient Egypt, as is evident from the glass beads, jars, figures, and ornaments discovered in the tombs.[45]Recent archeology has uncovered the remains of an ancient Egyptian glass factory.[46]

Medicine

Ancient Egyptian physicians were well renowned in the ancient near-East for their healing skills, and medical papyri show that they relied on thorough patient examinations and treatments based on a combination of natural product derived remedies, prayers, and protective amulets. Wounds were treated by bandaging with raw meat, honey was used to prevent infection, and opium was used to relieve pain. Garlic and onions were used regularly to promote good health and were thought to relieve asthma symptoms. Ancient Egyptian surgeons stitched wounds, set broken bones, and amputated diseased limbs, but recognized that some injuries were so serious that the only advice they could offer was to "Moor [the patient] at his mooring stakes, until the period of his injury passes by..." in other words, until the patient died.

Mathematics

Texts such as the Rhind Mathematical Papyrus show that the ancient Egyptians could perform addition, subtraction, multiplication, division, and calculation of the surface areas of rectangles, triangles, circles and even spheres. Although the ancient Egyptians were not familiar with the concept of pi, they were able to approximate the areas of circles by subtracting 1/9th of the circle's diameter and squaring the remainder. They could also calculate the volumes of boxes and pyramids, and were comfortable using fractions.

The golden ratio seems to be reflected in many constructions, such as the Egyptian pyramids,[47] however, some scholars assert that this may be the consequence of combining the use of knotted ropes with an intuitive sense of proportion and harmony.[48]

Open problems and scientific inquiry

Ancient Egypt is a fertile field for scientific inquiry, scholarly study, religious inspiration, and open speculation. Speculation and inquiry include the degree of sophistication of ancient Egyptian technology, and several open problems exist concerning real and alleged ancient Egyptian achievements. Certain artifacts and records do not correspond with conventional technological development systems.

It is not known why there seems to be no neat progression to an Egyptian Iron Age as in other developing cultures nor why the historical record shows the Egyptians possibly taking a long time to begin using iron. A study of the rest of Africa could point to the reasons: Sub-Saharan Africa confined their use of the metal to agricultural purposes for many centuries. The ancient Egyptians had a much easier form of agriculture with the annual Nile floods and fertile sediment delivery and strong metal tools to till soil were unnecessary. It should be stressed that while steel is derived from iron, it is by no means an intuitive leap. Small percentages of impurities can ruin a batch of molten iron, preventing it from becoming steel. Copper alloys are much more robust metallurgically and naturally plentiful in their environment. Several naturally occurring proportions of zinc, arsenic, tin, phosphorus will combine with copper and improve the properties of bronze. Bronze is stronger than iron, and does not rust, so to prefer bronze in this context is entirely rational. Given iron's greater abundance, it is likely that the Iron Age began when demand for 'any metal' outstripped supply of the 'quality metal' - bronze.

The exact date the Egyptians started producing glass is debated. There is some question whether the Egyptians were capable of long distance navigation in their boats and when they became knowledgeable sailors.

Beekeeping is known to have been particularly well developed in Egypt, as accounts are given by several Roman writers — Virgil, Gaius Julius Hyginus, Varro, and Columella. It is unknown whether Egyptian beekeeping developed independently or as an import from Southern Asia.

The Dromedary, domesticated first in Arabia, was introduced into Egypt during the 500s B.C., shortly before the Classical period of Greece began and although often thought as associated with Egypt by modern readers, camels evolved in the Western Hemisphere.[citation needed]
