[Footnote 107: The dates are uncertain. In general, on these synods see FREISEN, _op. cit._, 782-84; GEFFCKEN, _op. cit._, 55-57; and especially ESMEIN, _op. cit._, II, 64-69; who gives a clear summary of their decrees. _Cf._ PERRONE, _De mat. christ._, III, 332, 338 ff.] [Footnote 108: ESMEIN, _op. cit._, II, 69.] [Footnote 109: C. ix of the decree runs: "Si quis necessitate inevitabili cogente in alium ducatum seu provinciam fugerit, aut seniorem suum, cui fidem mentiri non poterit, secutus fuerit, et uxor ejus, cum valet et potest, amore parentum aut rebus suis, eum sequi noluerit, ipsa omni tempore, quamdiu vir ejus, quem secuta non fuerit, vivet, semper innupta permaneat. Nam ille vir ejus ... si se abstinere non potest, aliam uxorem cum poenitentia potest accipere." _Cf._ ESMEIN, _op. cit._, II, 66, note. In contrast with this decision, the Synod of Compiègne forbids both parties to remarry when the husband abandons his wife in order to escape private vengeance: _ibid._, 66.] [Footnote 110: ESMEIN, _op. cit._, II, 68; I, 325: _ap._ c. vi, decree of Verberie. _Cf._ also FREISEN, _op. cit._, 788; and CIGOI, _Unauflös. der ch. Ehe._, 74, who regards this synod more as an imperial diet than an ecclesiastical assembly, and so excuses its action. _Cf._ HEFELE, _Konzilien-Geschichte_, III, 537.] Even more striking is the decree of Compiègne regarding the effect of religious vows. When by agreement either partner enters the cloister, the spouse remaining in the world has the right of remarriage. To this decision, so sharply in contrast with the mature doctrine of the canon law, it is significant that a papal delegate to the synod, Bishop George of Ostia, gave his consent. The severer and more orthodox principle had been followed by the Synod of Verberie, which prohibits the man from remarriage when he suffers his wife to take the veil.[111] Both decrees permit separation on various other grounds, such as error of condition and certain degrees of affinity, which, under the dangerous guise of nullity, "constitute veritable exceptions to the rule" that the nuptial tie cannot be dissolved.[112] [Footnote 111: ESMEIN, _op. cit._, II, 65.] [Footnote 112: These decrees are for the most part included in the collection of Gratian; "mais il se fera tout un travail pour les mettre d'accord avec la règle triomphante de l'indissolubilité; elles contribueront néanmoins à introduire, dissimulées sous la forme de nullités, de véritables exceptions à cette règle."--ESMEIN, _op. cit._, II, 69.]
