Chronology

Chronology (from

Chronology is the science of locating historical events in time. It relies mostly upon

growth rings in their wood to known year-by-year reference sequences in the region to reflect year-to-year climatic variation. Dendrochronology is used in turn as a calibration reference for radiocarbon dating
curves.

Calendar and era

The familiar terms

epoch
is the date (year usually) when an era begins.

Ab Urbe condita era

Ab Urbe condita is Latin for "from the founding of the City (Rome)",[4] traditionally set in 753 BC. It was used to identify the Roman year by a few Roman historians. Modern historians use it much more frequently than the Romans themselves did; the dominant method of identifying Roman years was to name the two consuls who held office that year. Before the advent of the modern critical edition of historical Roman works, AUC was indiscriminately added to them by earlier editors, making it appear more widely used than it actually was.

It was used systematically for the first time only about the year 400, by the Iberian historian

Orosius. Pope Boniface IV, in about the year 600, seems to have been the first who made a connection between these this era and Anno Domini
. (AD 1 = AUC 754.)

Astronomical era

Dionysius Exiguus' Anno Domini era (which contains only calendar years AD) was extended by

Joseph Scaliger) and with it an astronomical era into use, which contains a leap year zero, which precedes the year 1 (AD).[5]

Prehistory

While of critical importance to the historian, methods of determining chronology are used in most disciplines of science, especially astronomy, geology, paleontology and archaeology.

In the absence of

William Flinders Petrie pioneered sequence dating to penetrate pre-dynastic Neolithic times, using groups of contemporary artefacts deposited together at a single time in graves and working backwards methodically from the earliest historical phases of Egypt. This method of dating is known as seriation
.

Known wares discovered at strata in sometimes quite distant sites, the product of trade, helped extend the network of chronologies. Some cultures have retained the name applied to them in reference to characteristic forms, for lack of an idea of what they called themselves: "The

Beaker People" in northern Europe during the 3rd millennium BCE, for example. The study of the means of placing pottery and other cultural artifacts into some kind of order proceeds in two phases, classification and typology: Classification creates categories for the purposes of description, and typology seeks to identify and analyse changes that allow artifacts to be placed into sequences.[6]

Laboratory techniques developed particularly after mid-20th century helped constantly revise and refine the chronologies developed for specific cultural areas. Unrelated dating methods help reinforce a chronology, an axiom of corroborative evidence. Ideally, archaeological materials used for dating a site should complement each other and provide a means of cross-checking. Conclusions drawn from just one unsupported technique are usually regarded as unreliable.

Synchronism

The fundamental problem of chronology is to synchronize events. By synchronizing an event it becomes possible to relate it to the current time and to compare the event to other events. Among historians, a typical need is to synchronize the reigns of kings and leaders in order to relate the history of one country or region to that of another. For example, the Chronicon of Eusebius (325 A.D.) is one of the major works of historical synchronism. This work has two sections. The first contains narrative chronicles of nine different kingdoms: Chaldean, Assyrian, Median, Lydian, Persian, Hebrew, Greek, Peloponnesian, Asian, and Roman. The second part is a long table synchronizing the events from each of the nine kingdoms in parallel columns.

By comparing the parallel columns, the reader can determine which events were contemporaneous, or how many years separated two different events. To place all the events on the same time scale, Eusebius used an

Pentateuch. According to the computation Eusebius used, this occurred in 5199 B.C. The Chronicon of Eusebius was widely used in the medieval world to establish the dates and times of historical events. Subsequent chronographers, such as George Syncellus (died circa 811), analyzed and elaborated on the Chronicon by comparing with other chronologies. The last great chronographer was Joseph Justus Scaliger (1540-1609) who reconstructed the lost Chronicon and synchronized all of ancient history in his two major works, De emendatione temporum (1583) and Thesaurus temporum (1606). Much of modern historical datings and chronology of the ancient world ultimately derives from these two works.[7] Scaliger invented the concept of the Julian Day which is still used as the standard unified scale of time for both historians and astronomers.[citation needed

In addition to the literary methods of synchronism used by traditional chronographers such as Eusebius, Syncellus and Scaliger, it is possible to synchronize events by archaeological or astronomical means. For example, the
