This is the first part of a new series: "Ruling Queens of Númenor & Silmariën" This is obviously Silmariën.
Silmariën was the daughter of Tar-Elendil, the fourth King of Númenor. From the days of Elros Tar-Minyatur and up until that moment the first-born child had always been also the first-born son, and the one to inherit the Kingship. Nonetheless, even if Silmariën was the first-born child of the King, she was also a female and thus not entitled to inherit. At that time, and following the model of the great Elven Kingdoms, the rule of the land was inherited via agnatic primogeniture (to be inherited by the first-born son, excluding all lines descended from females, unless male lines were completely extinguished). Because of this reason, Silmariën was passed over in favour of her brother Tar-Meneldur. But it is said that she was Tar-Elendil's favourite child, or perhaps that is a legend, and it was truly because the Kings of Nñumenor of earlier days were far-sighted, but it is the case that Tar-Elendil did give the Ring of Barahir, a capital heirloom of the line of Elros, to Silmariën for her and her children to keep. She perhaps received too the sword Narsil then, but what is sure is that at the time of her marriage to Eradan they were made the first Lords of Adúnië, second only to the King in power. The line of the Lords of Adúnië would withstand the trials of time; they would become the leaders of the elendili (or elf-friends) and survive to see the Fall of Númenor. Then extinguished all royal lines, the descendants of Silmariën would become Kings in Middle –Earth in the Númenorean realms in exile: Elendil, and his sons Isildur and Anárion.
As you can see (I hope) she is wearing the Ring of Barahir. The future tree of Gondor is embossed in the pillar she rests upon, and the winged helmet is a foreshadowing of the future winged crown of Elendil.
This is the second part of a new series: "Ruling Queens of Númenor & Silmariën" This is Tar-Ancalimë
Tar-Ancalimë, the daughter of Tar-Aldarion, was the seventh ruler and first Ruling Queen of Númenor. Tar-Aldarion, the sixth ruler of Númenor, had only one child: a daughter, Ancalimë. He changed the law of inheritance in Númenor to allow equal cognatic primogeniture, under which rule would pass to the oldest child of the ruler, whether male or female. This revised law had brutal conditions. It was only valid if the daughter married and produced an heir by a certain age, and if she married another member of the royal family. All this was partially to prevent another marriage as disastrous as that between Tar-Aldarion and Erendis, the failure of which Aldarion attributed to her lack of royal blood, and the life-span disparity; but also to prevent control of the crown passing into the hands of another family. Raised by her mother, Ancalimë had an inherent mistrust of all men, and her mother’s tragic married life made her choice very difficult. She was disinclined to marry, but then the crown would go to her cousin Soronto. Finally she married the nobleman Hallacar, son of Hallatan of Hyarastorni. Both Tar-Ancalimë and Hallacar were fifth-generation descendants of King Vardamir Nólimon, and the marriage was not one of love. The Queen aimed to produce an heir in order to secure her throne from her first cousin Soronto. Following the birth of their son, future King Tar-Anárion, Hallacar and Tar-Ancalimë lived apart. But this made her life troubled and her heart hard to anybody. Her own family became afraid of her in her latter days. It is through her though, that the terrible condition that imposed a woman should marry to become Queen was dropped.
In the picture, Tar-Ancalimë is crowning herself. It is an allegoric manner to make her choice apparent. She had the choice to refuse the crown and live apart from the Court she so loathed. Instead she sacrificed her chance to ever find love to become Queen in a very conscious decision, and willingly trapped herself in a loveless marriage she would have better liked to avoid.
