Ways dating artefacts
Unfortunately, after many years of analysis he was not able to confirm the correlation he sought.Dendrochronology is the oldest method, having been introduced over a century ago by an American astronomer, Professor A E Douglass.
If research into other sources of information also fails to throw light on the building's history, resort may be made to the various scientific methods of dating.
This article outlines three of the most important methods currently used for dating buildings or, in a complex situation, the order of construction within the building.
None is infallible and before embarking on an extensive dating survey, due thought must be given to what might be achieved and which methods might be the more successful. Whilst earlier types of wooden joints may be copied in later buildings and earlier styles may be reintroduced in later periods to confound the conservationist or historian, any reuse of older materials should become obvious by the use of the chronometrical methods described here.
The incorporation of ancient bog oak into a building, no matter how intricately carved or jointed, would immediately become obvious to the chronologist, as would timber renovations.
Upon encountering a new site, the archaeologist immediately requires information about its age in order to set it in context with other sites.
In research into our heritage the conservationist or architect may be able to date the general period of a building he is working with from either the situation, materials of construction, type of timber joints or other stylistic features.
