Managing your learning: Time lines

The time line provides a study tool that allows you to organize information that is presented chronologically. Time lines would be effective to use in classes in which you present historical, biological and other developments.

To make the order clear and to show the sequence of events, we mention dates and time, and we also use various links and connectives.

Written communication has been the centre of civilization for centuries. However, putting thoughts down in a written form wasn’t always easy or practical. Paper has a long history, beginning with the ancient Egyptians and continuing to the present day. It has largely survived the test of time but now it is facing a new challenge from its electronic equivalent. A particularly fruitful way to look at the evolution of paper is to study how it has changed over time.

3500 BC

Sumerians use cuneiform* alphabet, pressed in clay with a triangular stylus. Clay tablets were dried and/or fired for longevity. Some even had clay envelopes,' which were also inscribed.

3000 BC

Egyptians created Papyrus, a material made from thinly cut strips from the stem of Cyprus Papyrus plant.

2400 BC

Date of the earliest surviving papyrus scroll with writing.

200 BC

Both Greeks and Romans used wax tablets, framed and backed with wood, for note taking, orders, correspondence, and other temporary communication.

197-159 BC

In the Middle East, near Pergamum, large herds of cattle were raised for skins to be made into what we now call 'parchment.' It was the most popular material for manuscripts until the 12th century.

105 AD

Papermaking was invented in China by Ts'ai Louen. Material used: plant bark*, discarded cotton and old fishnets.

Papermaking reached Southern Italy, where, until quite recently, some of the oldest handmade paper mills* in Italy were operating in the Naples area.

1448

Johann Gutenberg invented the printing press.

1700 C.

Tremendous increase in papermaking led to a serious shortage of raw materials.

1843

1854

Mellier Watt patented a chemical pulp.

Late 18-th

Nicholas Luis Robert created a machine that could produce a seamless length of paper.

Paper production became industrialized with the advent of steam-driven paper making machines.

1950s

New material and fillers were used, new processed chemicals and dyers* were developed.
