A concordance to The Prophecies of Nostradamus' 1568 Lyon edition is thoroughly detailed in its presentation. This includes cross-referencing combined form words both under the first letter and under the first letter after the abbreviated word attached. The case is perfectly maintained, with attention given to symbols appearing in the quatrains, most importantly to ampersands, periods, commas, and colons. Additionally, quatrains that have been routinely attributed to Nostradamus are also included in this concordance, which appear in later editions (such as the 1630 reprint) and listed as additions to Centurie VII, Centurie X, Centurie XI and Centurie XII.
