1. Technology in Historical Ages

2. Historical Periods
Ancient Civilizations (Mesopotamia, Egypt, India, China, Greece, Rome)
The Middle Ages (Medieval Time Period)
from 476 AD – 1500 AD
The Renaissance
from 1350 – 1550 (Italy)

3. Mesopotamia
Mesopotamia is one of the cradles of human civilization. Here, the earliest cities in world history appeared, about 3500 BC.

4. Mesopotamia
A dense population grew up along the Tigris and Euphrates and their branches in the centuries after 5000 BC.
By 3500 BC, cities had appeared. The surplus food grown in this fertile landscape enabled the farming societies to feed a class of people who did not need to devote their lives to agriculture. These were the craftsmen, priests, scribes, administrators, rulers and soldiers who made civilization possible.

5. Mesopotamia The Sumerian language became the first to be written
down in world history.
The first script to be used was
based on pictures and appeared
around 3500 BC.
By 3000 BC the pictograms (of which there were more than a thousand) had become highly stylized, and were losing their original meanings. They were gradually becoming more "phonetic" - that is, reflecting spoken words.

6. Ancient Egyptians
The Egyptians invented and used many simple machines, such as the ramp to aid construction processes.
How did this allow them to build bigger and better buildings?

7. Ancient Egyptians
They were among the first to extract gold by large- scale mining using fire-setting, and the first recognizable map. Egyptian paper, made from papyrus, and pottery was mass produced and exported throughout the Mediterranean basin.

8. India
India is notable for its early application of city planning and sanitation technologies. Cites in the Indus Valley offer some of the first examples of closed gutters, public baths, and communal granaries.
India was also at the forefront of seafaring technology . Ship construction is vividly described in an ancient Indian text on Shipbuilding.

9. India
Indian construction and architecture suggests an understanding of materials engineering, hydrology, and sanitation.
Ancient Indian culture was also pioneering in its use of vegetable dyes, cultivating plants including indigo and cinnabar. Many of the dyes were used in art and sculpture.
The use of perfumes demonstrates some knowledge of chemistry, particularly distillation and purification processes.

10. China
Major technological contributions from China include early seismological detectors, matches, paper, cast iron, the iron plow, the wheelbarrow, the suspension bridge, the parachute, natural gas as fuel, the magnetic compass, the raised-relief map, the propeller, the crossbow, and gun powder.
Other Chinese inventions include the paddle wheel boat, block printing and movable type, phosphorescent paint, chain drive, the spinning wheel, and solid rocket fuel!

11. Greece
Greek engineers invented many technologies and improved upon pre-existing technologies. They were unique in their ability to combine scientific research with the development of new technologies.
Heron of Alexandria invented a basic steam engine, watermill and windmill.

12. Greece
Other Greek inventions include torsion catapults, pneumatic catapults, crossbows, cranes, organs, the keyboard mechanism, gears, screws, refined parchment, showers, vending machines, and automatic doors.
Archimedes invented several machines. One example is the Archimedean screw.

13. Greece
Greek architects were responsible for the first true domes, and were the first to explore the Golden ratio and its relationship with geometry and architecture.
Greek engineers constructed monumental lighthouses and devised the first central heating systems.

14. Ancient Rome The Roman Empire lasted from 753 BC to the 5th Century.
Many inventions and innovations took place in ancient Rome.

15. The Middle Ages
The Middle Ages were rife with wars, which led to great developments in weaponry and warfare. During the Middle Ages a number of inventions changed the way that battles were fought. For example, gunpowder contributed to the later invention of cannons, which changed the way battles were fought both on the land and at sea.

16. The Middle Ages Other important weaponry inventions include: The lance
The longbow
The crossbow
The flail
Armor
Chainmail

17. The Middle Ages
From navigation to steering and power, everything about the way boats and sailors worked together was changed, creating the Age of Exploration.
Important nautical inventions include:
The compass
Traverse boards
Astrolabes
Cross-staffs
Oars
Rudder

18. The Middle Ages
Farming inventions enabled the people of the Middle Ages to increase their food production, helping to feed a growing population. The changes to these farming processes helped to save time, produce more food and better crops.  Three field crop rotation  Heavy plow  Horse harness  Windmills  Wheelbarrow  Horseshoes

19. The Middle Ages
Timekeeping was a concept that was vastly improved upon during the Middle Ages. The first major timekeeping invention was the hourglass, which was used to measure time while at sea as well as on the land. The minute glass was also developed during this time.
The sundial was another simple yet highly effective timekeeping device that was developed during the Middle Ages.
Much later into the Middle Ages was the invention of the clock, which provided a much more accurate sense of time keeping, order and routine. To begin with these early mechanical clock struck only at the hour, and did not include hands.

20. The Middle Ages
There are a number of general inventions which dramatically changed the shape of society.
Eyeglasses
Weighing scales
Artesian wells
Water mills
Quarantine is an important concept that we use in modern medicine that came from the Middle Ages.

21. The Renaissance
The Renaissance was a time of creativity and change in Europe. It was a rebirth of cultural and intellectual pursuits after the stagnation of the Middle Ages. The Renaissance produced a golden age with many achievements in art, literature, and science, but most importantly, it produced a new concept of how people thought of themselves, each other, and the world around them.  The Renaissance was centered in Italy during the 1300s, before spreading throughout Europe in the 1500 and 1600s.

22. The Renaissance Telescope – Galileo
Submarine, anemometer, parachute, flying machine , revolving bridge and more! – Leonardo da Vinci
Printing Press – Johannes Gutenberg
