Letâs set aside the Statute of Miriel & FinwĂ« for now, and stick with just whatâs in the Silmarillion. Upon seeing Mirielâs intense weariness after FĂ«anorâs birth & hearing her say that she would bear no more children because of it, FinwĂ« isnât concerned for her health. Rather,
[âŠ] FinwĂ« was grieved, for the Noldor were in the youth of their days, and he desired to bring forth many children into the bliss of Aman [âŠ]
Emphasis mine. Itâs only after âMiriel languished stillâ for an unspecified period of time, failing to heal, that FinwĂ« goes to ManwĂ« for council (not Irmo or EstĂ«!!) and itâs ManwĂ« who âdelivered her to the care of Irmo in Lorien.â
Considering that âmanyâ of the Eldar seemingly saw his remarriage to Indis as a selfish action,
judging that if FinwĂ« had endured his loss and been content with the fathering of his mighty son, the courses of FĂ«anor would have been otherwise, and great evil might have been prevented [âŠ]
(emphasis mine), I donât think itâs a stretch to apply the same lens of selfishness to FinwĂ«âs earlier decisions regarding Miriel. And then thereâs a very obvious reason why FinwĂ«âs first appeal was to ManwĂ« rather than to EstĂ« and Irmo directly: because FinwĂ«âs primary concern was having more children, not having a healthy wife. And while EstĂ« and Irmo might have been able to deliver him the latterâ a wife who could bear more childrenâ Miriel has free will, and they canât give him back a wife whoâll agree to do so.
But ManwĂ«, as the highest authority of Valinor, might be able to do something about the fact that Mirielâs obstinance is preventing him from having the children that he wantsâ and considering that FinwĂ«âs eventual petition to remarry probably needed ManwĂ«âs assent to go before the Valar, it seems likely that he was correct!
Now, itâs likely that ManwĂ«âs initial judgement â within a context that seems to consider Mirielâs refusal of further childbearing an infringement upon FinwĂ«âs rights as husband and Kingâ was something like âIf your wife is healed in body and soul, she might also be healed of her refusal to bear more children. Letâs try that first.â
And the consequences were that Miriel was separated from her son and delivered to Lorien for healing, which was probably counterproductive, considering that she died very soon after arrival. And although thereâs a great deal more information about the Statute in other texts, the ultimate result of this horrible episode of Valinorean history is communicated in the Silmarillion itself. In death, Mirielâs exercising of reproductive autonomy stops inconveniencing FinwĂ«, who gets exactly what he wants: remarriage to Indis, and four more children.
