Historia Ecclesiastica Gentis Anglorum - Anno Domini

Bede's use of something similar to the anno Domini era, created by the monk Dionysius Exiguus in 525, throughout Historia Ecclesiastica was very influential in causing that era to be adopted thereafter in Western Europe. Specifically, he used anno ab incarnatione Domini (in the year from the incarnation of the Lord) or anno incarnationis dominicae (in the year of the incarnation of the Lord). He never abbreviated the term like the modern AD. Bede, like Dionysius, counted anno Domini from Christ's birth, not from Christ's conception. Within this work, he was also the first writer to use a term similar to the English before Christ. In book I chapter 2 he used ante incarnationis dominicae tempus (before the time of the incarnation of the Lord). However, the latter was not very influential—only this isolated use was repeated by other writers during the rest of the Middle Ages. The first extensive use of "BC" (hundreds of times) occurred in Fasciculus Temporum by Werner Rolevinck in 1474, alongside years of the world (anno mundi).
