How relative dating works

In the absence of written history, with its chronicles and king lists, late 19th century archaeologists found that they could develop relative chronologies based on pottery techniques and styles.

Unrelated dating methods help reinforce a chronology, an axiom of corroborative evidence.

Doc Oho: Mark Gatiss has gone on record to say that he doesn't find work for his husband, Ian Hallard, and that he gets the roles on his merits as an actor.

is the science of arranging events in their order of occurrence in time.

Radiocarbon dating estimates the age of formerly living things by measuring the proportion of carbon-14 isotope in their carbon content.

Dendrochronology estimates the age of trees by correlation of the various growth rings in their wood to known year-by-year reference sequences in the region to reflect year-to-year climatic variation.

Ten centuries after Bede, the French astronomers Philippe de la Hire (in the year 1702) and Jacques Cassini (in the year 1740), purely to simplify certain calculations, put the Julian Dating System (proposed in the year 1583 by Joseph Scaliger) and with it an astronomical era into use, which contains a leap year zero, which precedes the year 1 (AD).

While of critical importance to the historian, methods of determining chronology are used in most disciplines of science, especially astronomy, geology, paleontology and archaeology.Consider, for example, the use of a timeline or sequence of events.It is also "the determination of the actual temporal sequence of past events".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.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.
