The History of the Peloponnesian War is a historical account of the Peloponnesian War (431–404 BC), which was fought between the Peloponnesian League (led by Sparta) and the Delian League (led by Athens). It was written by Thucydides, an Athenian historian who also served as an Athenian general during the war. His account of the conflict is widely considered to be a classic and regarded as one of the earliest scholarly works of history. The History is divided into eight books.
Analyses of the History generally occur in one of two camps. On the one hand, some scholars such as J. B. Bury view the work as an objective and scientific piece of history. The judgment of Bury reflects this traditional interpretation of the History as "severe in its detachment, written from a purely intellectual point of view, unencumbered with platitudes and moral judgments, cold and critical."
On the other hand, in keeping with more recent interpretations that are associated with reader-response criticism, the History can be read as a piece of literature rather than an objective record of the historical events. This view is embodied in the words of W. R. Connor, who describes Thucydides as "an artist who responds to, selects and skillfully arranges his material, and develops its symbolic and emotional potential."
Historical method
Thucydides is considered to be one of the key figures in the development of Western history, thus making his methodology the subject of much analysis in the area of historiography.
Chronology
Thucydides is one of the first western historians to employ a strict standard of chronology, recording events by year, with each year consisting of the summer campaign season and a less active winter season. This method contrasts sharply with Herodotus.
Speeches
Thucydides also makes extensive use of speeches in order to elaborate on the event in question. While the inclusion of long first-person speeches is somewhat alien to modern historical method, in the context of ancient Greek oral culture, speeches are expected. These include addresses given to troops by their generals before battles and numerous political speeches, both by Athenian and Spartan leaders, as well as debates between various parties. Of the speeches, the most famous is the funeral oration of Pericles, which is found in Book Two. Being an Athenian general in the war, Thucydides heard some of these speeches himself. For the other speeches, he relied on eyewitness accounts.
These speeches are suspect in the eyes of Classicists, however, inasmuch as it is not clear to what degree Thucydides altered these speeches in order to elucidate better the crux of the argument presented. Some of the speeches are probably fabricated according to his expectations of, as he puts it, "what was called for in each situation" (1.22.1).
Neutrality
Despite being an Athenian and a participant in the conflict, Thucydides is often regarded as having written a generally unbiased account of the conflict with respect to the sides involved in it. In the introduction to the piece he states, "my work is not a piece of writing designed to meet the taste of an immediate public, but was done to last for ever" (1.22.4).
There are scholars, however, who doubt this. Ernst Badian, for example, has argued that Thucydides has a strong pro-Athenian bias. In keeping with this sort of doubt, other scholars claim that Thucydides had an ulterior motive in his Histories, specifically to create an epic comparable to those of the past such as the works of Homer, and that this led him to create a nonobjective dualism favoring the Athenians. The work does display a clear bias against certain people involved in the conflict, such as Cleon.
Role of religion
The gods play no active role in Thucydides' work. This is very different from Herodotus, who frequently mentions the role of the gods, as well as a nearly ubiquitous divine presence in the centuries-earlier poems of Homer. Instead, Thucydides regards history as being caused by the choices and actions of human beings.
Despite the absence of actions of the gods, religion and piety play critical roles in the actions of the Spartans, and to a lesser degree, the Athenians. Thus natural occurrences such as earthquake and eclipses were viewed as religiously significant (1.23.3; 7.50.4)
