Typology (archaeology)


In archaeology a typology is the result of the classification of things according to their physical characteristics. The products of the classification, i.e. the classes, are also called types. Most archaeological typologies organize portable artifacts into types, but typologies of larger structures, including buildings, field monuments, fortifications or roads, are equally possible. A typology helps to manage a large mass of archaeological data. According to Doran and Hodson, "this superficially straightforward task has proved one of the most time consuming and contentious aspects of archaeological research".

Typology is based on a view of the world familiar from Plato's metaphysics called essentialism. Essentialism is the idea that the world is divided into real, discontinuous and immutable ‘kinds’. This idea is the basis for most typological constructions, particularly of stone artefacts where essential forms are often thought of as ‘mental templates’, or combinations of traits that are favoured by the maker. Variation in artifact form and attributes is seen as a consequence of the imperfect realization of the template, and is usually attributed to differences in raw material properties or individuals' technical competences.

Although the principles were not clearly articulated, the application of basic typological techniques can occasionally be found in the work of early modern antiquaries. As early as the 1530s, John Leland successfully identified Roman bricks (under the misleading designation "Briton brykes") at several different sites, distinguishing them from more modern bricks by size and shape. Antiquaries began to recognise in the late 16th century that medieval monumental effigies represented with their legs crossed were likely to be older than those with straight legs. In the late 17th century, John Aubrey worked out crude evolutionary sequences based on typological distinctions for medieval architecture, handwriting, shield-shapes and costume. The outline of the development of medieval Gothic architecture was further refined in the 18th century, culminating in the clear sequence of styles published by Thomas Rickman in 1817.
