The scientific knowledge that Irish, English, and continental European scholars nurtured and developed during the years c. AD 500 to c. AD 1200 was assimilated, in the first place, from the wider Roman world of Late Antiquity. Time-reckoning, calendars, and the minute reckonings required to compute the date of Easter, all involved the minutiae of mathematics (incl. the original concept of ‘digital calculation’) and astronomical observation in a truly scientific fashion. In fact, the ‘Dark Ages’ were anything but dark in the fields of mathematics and astronomy.The first Science of Computus conference in Galway in 2006 highlighted the transmission of Late Antique Mathematical Knowledge in Ireland & Europe, the development of astronomy in Early Medieval Ireland & Europe and the role of the Irish in the development of computistical mathematics. The proceedings of that conference should, therefore, 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.

The system of numbering the years AD (Anni Domini, Years of the Lord) originated with Dionysius Exiguus. Dionysius drafted a 95-year table of dates for Easter beginning with the year 532 AD. Why Dionysius chose the year that he did to number as '1' has been a source of controversy and speculation for almost 1500 years. According to the Gospel of Luke (3.1; 3.23), Jesus was baptized in the 15th year of the emperor Tiberius and was about 30 years old at the time. The 15th year of Tiberius was AD 29. If Jesus was 30 years old in AD 29, then he was born in the year that we call 2 BC. Most ancient authorities dated the Nativity accordingly.Alden Mosshammer provides the first comprehensive study of early Christian methods for calculating the date of Easter to have appeared in English in more than one hundred years. He offers an entirely new history of those methods, both Latin and Greek, from the earliest such calculations in the late second century until the emergence of the Byzantine era in the seventh century. From this history, Mosshammer draws the fresh hypothesis that Dionysius did not calculate or otherwise invent a new date for the birth of Jesus, instead adopting a date that was already well established in the Greek church. Mosshammer offers compelling new conclusions on the origins of the Christian era drawing upon evidence found in the fragments of Julius Africanus, of Panodorus of Alexandria, and in the traditions of the Armenian church.
