 The best-known, previous to the 19th century, are those of the brothers Pithou (Paris, 1687), Freiesleben (Prague, 1728) and the Protestant canonist Böhmer (Halle-Magdeburg, 1747).The text of the latter edition differs from that of the Roman edition of 1582, and does not therefore possess practical utility.The edition of Richter (Leipzig, 1833–39) avoids this defect and is valuable for its critical notes.
