Later Greeks used a variety of writing implements- papyrus (which they got from Phoenician traders), parchment (which was made from the scraped hides of cattle, ship or goats), wooden tablets whitened with gypsum, wooden tablets coated with wax and, of course, more durable materials such as stone monuments and bronze plaques. These more permanent materials were often used for official inscriptions- laws of the city, treaties with other states, temple dedications, war memorials and such.

Early Greek writing runs from right to left- for the first line. The second line then runs from left to right and the direction of the lines alternate for the complete text. This kind of writing is called boustrophedon (as the ox turns- when he plows a field.) Later the left to right system, which we use today, became the standard. 

The Greek alphabet is still used for the Greek language today. The letters of the Greek alphabet are now also used as symbols for concepts in equations of the interrelated fields of mathematics and science—for example, the lowercase alpha (⍺) can be used to represent an angle in mathematics.

Herodotus is widely known as the "father of history": his Histories are eponymous of the entire field. Written between the 450s and 420s BC, Herodotus' work reaches about a century into the past, discussing 6th century BC historical figures such as Darius I of Persia, Cambyses II and Psamtik III, and alluding to some 8th century BC persons such as Candaules. The accuracy of Herodotus' works is debated.

Herodotus was succeeded by authors such as Thucydides, Xenophon, Demosthenes, Plato and Aristotle. Most were either Athenian or pro-Athenian, which is why far more is known about the history and politics of Athens than of many other cities. Their scope is further limited by a focus on political, military and diplomatic history, ignoring economic and social history(by Yayu)
