At any other location within the study area, the direction of the regional field can be obtained by spatial interpolation from the reference curves as illustrated by isogonic and isoclinic maps shown for selected times.

Local time-series of interpolated directions for other central European countries lacking reference curves might serve as master curves for magnetic dating.

Besides reviewing the basic principles of these methods, this article describes a number of applications, emphasizing explication of the method and solution of particular archaeological problems.

Does one need to have experienced something to know what it’s like? And, therefore, others –free of the virus- will be too.

For comparison's sake, directional records of comparable length from central Europe were also processed by the same curve building method.

For this purpose, all dated directional data (declination and inclination with statistics) were drawn from the GEOMAGIA50 database for France, Germany, the Ukraine and Moldavia, Bulgaria and Italy and transferred via their virtual geomagnetic poles to a reference point of their respective countries.

From this data set, reference curves of secular variation of the geomagnetic field direction were computed using hierarchical modelling and curve estimation by moving average technique.

This special exhibition unearths the stories behind four skeletons from the Museum of London’s 20,000-strong collection and four from burial grounds across Scotland.Archaeomagnetic direction and archaeointensity dating are regional pattern-matching techniques, whereas magnetic reversal dating is a global pattern-matching method.Secular variation dating using archaeomagnetic directions and archaeointensities has been used for Neolithic and younger cultures.Each skeleton exhibits pathologies that expose the multiple challenges of life in the past, from fractures and trauma, cancer and the effects of syphilis, to rickets, arthritis and tooth decay.Research has also shed new light on the grounds they were discovered in and the circumstances in which they were buried.In 1912 a small group of burials were discovered on the machair at Balevullin.Records show four skeletons were found, including a young child aged between 4 and 7 years old.For times before the advent of direct geomagnetic measurements a few centuries ago, information about the direction and intensity of the geomagnetic field can be obtained only in an indirect way, by measuring the remanent magnetism of certain rocks and sediments and baked archaeomagnetic material that have not been moved since the time of magnetisation.Archaeomagnetic dating is based on the comparison of directions, intensities or polarities with master records of change.This establishes Balevullin as a rare example of a Neolithic inhumation cemetery. Henderson Bishop, a wealthy Scottish businessman and pig farmer who led the excavation, describe how one of the skeletons was ‘collared’ by the Professor of Anatomy at the University of Glasgow for his museum.Supplemented by 32 new directions, the Hungarian archaeomagnetic data set now consists of 217 archaeologically dated directions ranging in age from 300 BC to 1800 AD.
