Liber Septimus

The Liber Septimus Latin for Seventh book may refer to one of three canonical collections of quite different return from a legal standpoint which are call by this title:

Seventh Book of Decretals, 1690

Pierre Mathieu Petrus Matthæus, a canonist of the sixteenth century, published in 1590, under the designation of "Septimus Liber Decretalium" 'Seventh Book of Decretals', a collection of canons arranged according to the ordering of the papal Decretals of Gregory IX, containing some Decretals of previous popes, especially of those from the reign of Sixtus IV 1464–71 to that of Sixtus V, in 1590. It was an entirely private collection and devoid of scientific value. Some editions of the "Corpus Juris Canonici" Frankfort, 1590; Lyons 1621 and 1671; Justus Henning Boehmer's edition, Halle, 1747 contained the text of this "Liber septimus" as an appendix.
