Image collection

Leicester University Archive

An archival collection of c. 1100 images of archaeological and archaeoastronomical interest has been available on-line since 1995.

     

     

Thousands of new images are (very!) gradually being made available— see here

Archaeoastronomy tools

 

Declination calculator

This basic declination calculator calculates the astronomical declination of any structural alignment given the true azimuth, horizon altitude, and terrestrial latitude. It applies a mean refraction correction to the observed altitude and (for geocentric lunar declinations) mean lunar parallax.

 

It is an interactive version of the “GETDEC” program referred to in Astronomy in Prehistoric Britain and Ireland (p. 169) with only the basic functionality included (i.e. no offsets etc.).

Horizon visualization from DTM data

Andrew Smith’s excellent “HORIZON” tool generates visualisations of horizon profiles annotated with azimuth, altitude and declination and showing rising and setting paths of the sun, moon and/or selected stars as desired.

 

 

Archival resources on this site

A few old programs, including the original GETDEC program, can still be found among archival resources held here on a back-up server at Leicester University. These include

  1. Horizon finder, a program by David Dearborn to scan an image and produce a digitised and calibrated horizon profile
  2. Pohualli, a Mesoamerican calendar conversion program by Arkadiusz Soltysiak and Arnold Lebeuf

Others are long obsolete. For example, GRIDLA and LAGRID have been superseded by several tools available on the web, such as (for the British National Grid) the Ordnance Survey’s Co-ordinate calculation spreadsheet.

Archaeoastronomy

… is the study of beliefs and practices relating to the sky in the past, especially in prehistory, and the uses to which people's know- ledge of the skies was put.
