5th International Conference
on the Science of Computus
July 11 - 13, 2014

http://www.nuigalway.ie/history/Computus_Conference/computusconference2014.html

The Science of Computistics - the mathematics required to calculate the date of Easter, and related topics (incl. astronomical observations and calculations) - straddles the fields of mathematics and astronomy, biblical interpretation and cosmology, empirical astronomical observation, and the perennial quest to understand the concepts of Time and Time-Reckoning. 'Since in the 7th century the leading experts on the computus were the Irish' (the verdict of Leofranc Holford-Strevens, The History of Time, a very short introduction [Oxford 2005] 56) it was entirely appropriate that the first landmark conference devoted to this topic should have taken place in Galway, as it did in 2006. It brought together, for the first time, the leading scholars in this field from all over the world, and the conference papersprovided a panorama of Early Medieval scientific knowledge, both in Ireland and in the rest of Western Europe, during the period of the so-called 'Dark Ages'. That first Conference was an outstanding success, and the proof is in the fact that we have had four others since, and are now looking forward to the fifth this coming July. In fact, the study of computistics has become synonymous with Galway, with the result that NUIG has become the permanent home for the Conference

The previous Science of Computus conferences in Galway highlighted

The transmission of Late Antique Mathematical Knowledge in Ireland & Europe
The Development of Astronomy in Early Medieval Ireland & Europe
The Irish role in the development of Computistical Mathematics
The use of computistics for purposes of prognostication

The Proceedings of the 1st (2006) Conference and of the 2nd (2008) have already been published, while those of the 3rd (2010) Conference will shortly go to press. The papers, as a rule, appeal equally to those interested in the history of science in Ireland and Europe, and in the origins of present-day mathematical and astronomical ideas, specialist scholars and the wider public.
